General Introduction
DTS-8001. System Introduction1.1 CDMA AbstractThe cellular system has a channel hand-off function that is used for collecting the information on the locations and movements ofradio mobile telephones from the cell site by automatically controlling several cell site through the setup of data transmissionroutes and thus, enabling one switching system to carry out the automatic remote adjustment. This is to maintain continuously thecall state through the automatic location confirmation and automatic radio channel conversion when the busy subscriber movesfrom the service area of one cell site to that of another by using automatic location confirmation and automatic radio channelconversion functions. The call state can be maintained continuously by the information exchange between switching systems whenthe busy subscriber moves from one cellular system area to the other cellular system area.In the cellular system, the cell site is a small-sized low output type and utilizes a frequency allocation system that considersmutual interference, in an effort to enable the re-use of corresponding frequency from a cell site separated more than a certaindistance. The analog cellular systems are classified further into an AMPS system, E-AMPS System, NMT system, ETACSsystem, and JTACS system depending on technologies used.Unlike the time division multiple access (TDMA) or frequency division multiple access (FDMA) used in the band limitedenvironment, the Code Division Multiple Access(CDMA) system which is one of digital cellular systems is a multi-accesstechnology under the interference limited environment. It can process more number of subscribers compared to other systems(TDMA system has the processing capacity three times greater than the existing FDMA system whereas CDMA system, about12~15 times of that of the existing system).CDMA system can be explained as follows: TDMA or SDMA can be used to enable each person to talk alternately or provide aseparate room for each person when two persons desire to talk with each other at the same time, whereas FDMA can be used toenable one person to talk in soprano, whereas the other in bass (one of the two talkers can carry out synchronization for hearingin case there is a bandpass filter function in the area of the hearer).Another method available is to make two persons to sing in different languages at the same time, space, and frequency whenwishing to let the audience hear the singing without being confused. This is the characteristics of CDMA.On the other hand, when employing the CDMA technology, each signal has a different pseudo-random binary sequence used tospread the spectrum of carrier. A great number of CDMA signals share the same frequency spectrum. In the perspective offrequency area or time area, several CDMA signals are overlapped. Among these types of signals, only desired signal energy isselected and received through the use of pre-determined binary sequence; desired signals can be separated and then, receivedwith the correlator used for recovering the spectrum into its original state. At this time, the spectrums of other signals that havedifferent codes are not recovered into its original state and instead, processed as noise and appears as the self-interference of thesystem. CHAPTER 1. System Introduction
2. Features and Advantages of CDMA Module2.1 Various Types of DiversitiesIn the CDMA broadband modulation(1.25MHz band), three types of diversities (time, frequency, and space) are used to reduceserious fading problems generated from radio channels in order to obtain high-quality calls.Time diversity can be obtained through the use of code interleaving and error correction code whereas frequency diversity canbe obtained by spreading signal energy to more wider frequency band. The fading related to normal frequency can affect thenormal 200~300kHz among signal bands and accordingly, serious affect can be avoided. Moreover, space diversity (also calledpath diversity) can be realized with the following three types of methods.First, it can be obtained by the duplication of cell site receive antenna. Second, it can be obtained through the use of multi-signalprocessing device that receives a transmit signal having each different transmission delay time and then, combines them. Third, itcan be obtained through the multiple cell site connection (Soft Handoff) that connects the mobile station and more than two cellsites at the same time.2.2 Power ControlThe CDMA system utilizes the forward (from a base station to mobile stations) and backward (from the mobile station to thebase station) power control in order to increase the call processing capacity and obtain high-quality calls. In case the originatingsignals of mobile stations are received by the cell site in the minimum call quality level (signal to interference) through the use oftransmit power control on all the mobile stations, the system capacity can be maximized.If the signal of mobile station is received too strong, the performance of that mobile station is improved. However, because ofthis, the interference on other mobile stations using the same channel is increased and accordingly, the call quality of othersubscribers is reduced unless the maximum accommodation capacity is reduced.In the CDMA system, forward power control, backward open loop power control, and closed loop power control methods areused. The forward power control is carried out in the cell site to reduce the transmit power on mobile stations less affected bythe multi-path fading and shadow phenomenon and the interference of other cell sites when the mobile station is not engaged inthe call or is relatively nearer to the corresponding cell site. This is also used to provide additional power to mobile stationshaving high call error rates, located in bad reception areas or far away from the cell site.The backward open loop power control is carried out in a corresponding mobile station; the mobile station measures powerreceived from the cell site and then, reversely increases/decreases transmit power in order to compensate channel changescaused by the forward link path loss and terrain characteristics in relation to the mobile station in the cell site. By doing so, allthe mobile office transmit signals in the cells are received by the cell site in the same strength.Moreover, the backward closed loop power control used by the mobile station to control power with the commands issued outby the cell site. The cell site receives the signal of each corresponding mobile station and compares this with the pre-setthreshold value and then, issues out power increase/decrease commands to the corresponding mobile station every 1.25 msec(800 times per second).By doing so, the gain tolerance and the different radio propagation loss on the forward/backward link are complemented.
2.3 Voice Encoder and Variable Data SpeedThe bi-directional voice service having variable data speed provides voice communication which employs voice encoderalgorithm having power variable data rate between the mobile telephone cell site and mobile station. On the other hand, thetransmit voice encoder performs voice sampling and then, creates encoded voice packets to be sent out to the receive voiceencoder, whereas the receive voice encoder demodulates the received voice packets into voice samples.One of the two voice encoders described in the above is selected for use depending on inputted automatic conditions andmessage/data; both of them utilize four-stage frames of 9600, 4800, 2400, and 1200 bits per second. In addition, this type ofvariable voice encoder utilizes adaptive threshold values when selecting required data rate. It is adjusted in accordance with thesize of background noise and the data rate is increased to high rate only when the voice of caller is inputted.Therefore, background noise is suppressed and high-quality voice transmission is possible under the environment experiencingserious noise. In addition, in case the caller does not talk, data transmission rate is reduced so that the transmission is carried outin low energy. This will reduce the interference on other CDMA signals and as a result, improve system performance (capacity,increased by about two times).2.4 Protecting Call ConfidentialityCDMA signals have the function of effectively protecting call confidentiality by spreading and interleaving call information inbroad bandwidth. This makes the unauthorized use of crosstalk, search receiver, and radio very hard substantially. Also includedis the encryption function on various authentication and calls specified in IS-95 for the double protection of call confidentiality.2.5 Soft HandoffDuring the soft hand, the cell site already in the busy state and the cell site to be engaged in the call later participate in the callconversion. The call conversion is carried out through the original call connection cell site, both cell sites, and then, new cellsite. This method can minimize call disconnection and prevent the user from detecting the hand-off.2.6 Frequency Re-Use and Sector SegmentationUnlike the existing analog cellular system, the CDMA system can reuse the same frequency at the adjacent cell and accordingly,there is no need to prepare a separate frequency plan. Total interference generated on mobile station signals received from thecell site is the sum of interference generated from other mobile stations in the same cell site and interference generated from themobile station of adjacent cell site. That is, each mobile station signal generates interference in relation to the signals of all theother mobile signals.Total interference from all the adjacent cell sites is the ratio of interference from all the cell sites versus total interference fromother mobile stations in the same cell site (about 65%). In the case of directional cell site, one cell normally uses a 120°sectorantenna in order to divide the sector into three. In this case, each antenna is used only for 1/3 of mobile stations in the cell siteand accordingly, interference is reduced by 1/3 on the average and the capacity that can be supported by the entire system is
increased by three times.2.7 Soft CapacityThe subscriber capacity of CDMA system is flexible depending on the relation between the number of users and service classes.For example, the system operator can increase the number of channels available for use during the busy hour despite the drop incall quality. This type of function requires 40% of normal call channels in the standby mode during the handoff support, in aneffort to avoid call disconnection resulting from the lack of channels.In addition, in the CDMA system, services and service charges are classified further into different classes so that more transmitpower can be allocated to high class service users for easier call set-up; they can also be given higher priority of using hand-offfunction than the general users.
3. Structure and Functions of CDMA ModuleThe mobile station of CDMA system is made up of a radio frequency part and logic/control (digital) part. The mobile station isfully compatible with the existing analog FM system. The mobile station antenna is connected with the transmitter/receiver via aduplexer filter so that it can carry out the transmit/receive function at the same time.The transmit frequency is the 25MHz band of 824~849MHz, whereas the receive frequency is the 25MHz band of 869~894MHz.The transmit/receive frequency is separated by 45MHz. The RF signal from the antenna is converted into intermediatefrequency(IF) band by the frequency synthesizer and frequency down converter and then, passes the bandpass SAW filter havingthe 1.25MHz band. IF output signals that have been filtered from spurious signal are converted into digital signals via an analog-to-digital converters(ADC) and then, sent out respectively to 5 correlators in each CDMA de-modulator. Of these, one is called asearcher whereas the remaining 4 are called data receiver(finger). Digitalized IF signals include a great number of call signalsthat have been sent out by the adjacent cells. These signals are detected with pseudo-noise sequence (PN Sequence). Signal tointerference ratio (C/I) on signals that match the desired PN sequence are increased through this type of correlation detectionprocess. Then, other signals obtain processing gain by not increasing the ratio. The carrier wave of pilot channel from the cellsite most adjacently located is demodulated in order to obtain the sequence of encoded data symbols. During the operation withone cell site, the searcher searches out multi-paths in accordance with terrain and building reflections. On three data receivers,the most powerful four paths are allocated for the parallel tracing and receiving. Fading resistance can be improved a great dealby obtaining the diversity combined output for de-modulation. Moreover, the searcher can be used to determine the mostpowerful path from the cell sites even during the soft handoff during the two cell sites. Moreover, four data receivers areallocated in order to carry out the de-modulation of these paths. Data output that has been demodulated change the data string inthe combined data row as in the case of original signals(deinterleaving), and then, are de-modulated by the forward errorcorrection decoder which uses the Viterbi algorithm.On the other hand, mobile station user information sent out from the mobile station to the cell site pass through the digital voiceencoder via a mike. Then, they are encoded and forward errors are corrected through the use of convolution encoder. Then, theorder of code rows is changed in accordance with a certain regulation in order to remove any errors in the interleaver. Symbolsmade through the above process are spread after being loaded onto PN carrier waves. At this time, PN sequence is selected byeach address designated in each call.Signals that have been code spread as above are digital modulated (QPSK) and then, power controlled at the automatic gaincontrol amplifier (AGC Amp). Then, they are converted into RF band by the frequency synthesizer synchronizing these signals toproper output frequencies.Transmit signals obtained pass through the duplexer filter and then, are sent out to the cell site via the antenna.

1. OverviewIRT3000 receives modulated digital signals from the MSM of the digital circuit and then, changes them into analogsignals by the digital/analog converter (DAC, D/A Converter) in order to create baseband signals. Created basebandsignals are changed into IF signals by IFT3000 and then, fed into the Mixer after going through AGC. IF signals thathave been fed are mixed with the signals of VCO and changed into the RF signals and then, they are amplified at thePower AMP. Finally, they are sent out to the cell site via the antenna after going through the isolator and duplexer.2. RF Transmit / Receive Part2.1 CDMA Transmit End8 bit I and Q transmit signals are inputted into 2 DACs (DIGITAL-TO-ANALOG CONVERTER) from the outputterminal TX_IQDATA0 ~ TX_IQDATA7 of MSM through the input terminals TXD0~TXD7 of BBA. Transmitsignal input speed is two times of TXCLK+, TXCLK- which are two transmit/receive reference frequency.Among transmit signals being inputted, signals are inputted into I signal DAC when the transmit clock is in the riseedge, whereas signals are inputted into Q Signal DAC during the drop edge. I and Q transmit signals arecompensated and outputted at MSM in order to compensate the 1/2 clock time difference generated betweenreference clocks. In the signals coming out from the output terminal of DAC, there are spurious frequencyingredients resulting from DAC output transition edge and parasite ingredients, transmit clock frequencies andharmonics which are unwanted signals. Accordingly, spurious ingredients are removed by passing the signalsthrough LPF of passband 6.30KHz. Unlike the receive end, the transmit end LPF requires no OFFSET adjustment.Analog baseband signals that have passed the CDMA LPF are mixed with I and Q signals of frequency 130.38 MHz(260.76 MHz created in the BBA internal VCO are divided by half into frequency 130.38MHz having the phasedifference of 90 degrees) in two mixers. The mixed signals are added again and converted into IF frequency 130.38MHz ±630 KHz (CDMA Spread Power Density Modulated Signals) and then, outputted.2.2. Tx IF/Baseband Processors, IFT3000 (U105)The IFT3000 includes digital-to-analog converters(DAC) for converting digital baseband to analog baseband, low-pass filters, a mixer for up-converting to IF and an 85 dB dynamic range Tx AGC amplifier. The IFT3000 includesa fully programmable phase-locked loop(PLL) for generating Tx LO and IF frequencies. The IFT3000 also has an 8-bit general purpose ADC with three selectable inputs for monitoring battery level, RF signal strength and phone CHAPTER 3. Circuit Description
temperature. 2.3. Upconverter (U104)Upconverters made up of a mixer part and Driver AMP part. The mixer part is used to receivedouble-balanced OUT+ and OUT- of transmit AGC from baseband and mix the output of VCO (U171) with UHFoutput signal, whereas the Amp part is used to buffer the output of this mixer. U105 has the operation range ofRF500MHz~1500MHz and has the conversion gain of 0 dB. In addition, the suppression of spurious signals whichare unwanted noise is about 30 dBc when being compared to RF output. The IF input signal range of the mixer isDC~200MHz. The isolation on RF output terminal and LO signal input terminal at the IF input terminal is 30dB.The range of LO signal that can be inputted is 300~1700MHz and power level is -6~0 dBm.2.4. Transmit Bandpass Filter (F102, F103)Transmit signals that have been converted from IF signals into RF signals after passing through the upconverterU105 are inputted into the Power Amp U102 after passing once again through RF BPF F102 in order to filter outnoise signals amplified during the amplification of RF signals after going through upconverter(U105). This is carriedout in order to create power level inputted to the Power AMP via RF BPF F102. IL of two RF BPFs is 4dB as amaximum, whereas the ripple in the passing band is 2dB(maximum). The degree of the suppression of transmitsignals on receive band is at least 20dB or greater. The maximum power that can be inputted is about 25dBm.2.5. Power Amplifier (U102)The power amplifier U102 that can be used in the CDMA and FM mode has linear amplification capability,whereas in the FM mode, it has a high efficiency. For higher efficiency, it is made up of one MMIC (MonolithicMicrowave Integrated Circuit) for which RF input terminal and internal interface circuit are integrated onto one ICafter going through the AlGaAs/GaAs HBT (heterojunction bipolar transistor) process. The module of poweramplifier is made up of an output end interface circuit including this MMIC. The maximum power that can beinputted through the input terminal is +17dBm and conversion gain is about 28dB. RF transmit signals that havebeen amplified through the power amplifier are sent to the duplexer and then, sent out to the cell site through theantenna in order to prevent any damages on circuits, that may be generated by output signals reflected from theduplexer and re-inputted to the power amplifier output end.
2.6. Description of Frequency Synthesizer Circuit2.6.1 Voltage Control Temperature Compensation Crystal Oscillator(U174, VCTCXO)The temperature range that can be compensated by U174 which is the reference frequency generator of mobileterminal is -30 ~ +80 degrees. U174 receives frequency tuning signals called TRK_LO_ADJ from MSM as0.5V~2.5V DC via R and C filters in order to generate the reference frequency of 19.68MHz and input it into thefrequency synthesizer of UHF band. Frequency stability depending on temperature is ± 2.0 ppm.2.6.2 UHF Band Frequency Synthesizer (U172)Reference frequency that can be inputted to U172 is 3MHz~40MHz. It is the dual modefrequency synthesizer (PLL) that can synthesize the frequencies of UHF band 50MHz~1200MHz and IF band20MHz~300MHz. U172 that receives the reference frequency of 19.68MHz from U174 creates 30kHz comparisonfrequency with the use of internal program and then, changes the frequency of 900MHz band inputted from X200which is the voltage adjustment crystal oscillator into the comparison frequency of 30kHz at the prescaler in U172.Then, two signal differences are calculated from the internal phase comparator. The calculated difference isinputted to DC for adjusting the frequency of U174 through U172 No.2 PIN and external loop filter in order togenerate UHF signals. In addition, outputs of other PIN17 are inputted into BBA after going through the VRACTORdiode and tank circuit so that the outputs of BBA internal receive end VCO are adjusted to 170.76MHz.2.6.3 Voltage Control Crystal Oscillator (U171)U171 that generates the LO frequency (900MHz) of mobile terminal receives the output voltage of PLL U172 andthen, generates the frequency of 954MHz at 0.7V and the frequency of 980MHz at 2.7V. The sensitivity on controlvoltage is 23MHz/v and the output level is 1dBm(maximum). Since LO frequency signal is very important for thesensitivity of mobile terminal, they must have good spurious characteristics. U174 is -70dBc(maximum).3. Digital/Voice Processing Part 3.1 OverviewThe digital/voice processing part processes the user's commands and processes all the digital and voice signalprocessing in order to operate in the phone. The digital/voice processing part is made up of a receptacle part, voiceprocessing part, mobile station modem part, memory part, and power supply part.
3.2 Configuration3.2.2 Voice Processing PartThe voice processing part is made up of an audio codec into digital voice signals and digital voice signals intoanalog voice signals, amplifying part for amplifying the voice signals and sending them to the ear piece, amplifyingpart that amplifies ringer signals coming out from MSM3000, and amplifying part that amplifies signals coming outfrom MIC and transferring them to the audio processor.3.2.3 MSM (Mobile Station Modem) PartMSM is the core elements of CDMA terminal and carries out the functions of CPU, encoder, interleaver,deinterleaver, Viterbi decoder, Mod/Demod, and vocoder.3.2.4 Memory PartThe memory part is made up of a flash memory, SRAM for storing data, and EEPROM.3.2.5 Power Supply PartThe power supply part is made up of circuits for generating various types of power, used for the digital/voiceprocessing part. +4.2V from external DC (+6V) is fed into five regulators(U605,U603,U602,U604,U606). The five regulators produces +3.0V for the IFR3000(U204) and for Tx Parts.3.3 Circuit Description

In addition, digital audio signals outputted from MSM3000 are convertedinto analog signals after going through the audio codec to be amplified. and then transferred to the ear piece.3.3.3 MSM PartMSM3000, which is U301, is the core element of CDMA system terminal that includes ARM7TDMImicroprocessor core. It is made up of a CPU, encoder, interleaver, deinterleaver, Viterbi decoder, MOD/DEM, andvocoder. MSM3000, when operated in the CDMA mode, utilizes CHIPX8 (9.8304MHz) as the reference clock thatis received from IFR3000, and uses TCXO (19.68MHz) that is received from U174. CPU controls the terminaloperation. Digital voice data that have been inputted are voice-encoded and variable-rated. Then, they areconvolutionally encoded so that error detection and correction are possible. Coded symbols are interleaved in orderto cope with multi-path fading. Each data channel is scrambled by the long code PN sequence of the user in order toensure the confidentiality of calls.Moreover, binary quadrature codes are used based on Walsh functions in order to discern each channel.
Data created thus are 4-phase modulated by one pair of Pilot PN code and they are used to create I and Q data.When received, I and Q data are demodulated into symbols by the demodulator and then, de-interleaved in reverseto the case of transmission. Then, the errors of data received from Viterbi decoder are detected and corrected. Theyare voice decoded at the vocoder in order to output digital voice data.The MSM3000 has a improved feature not found on the MSM2300. The MSM3000 supports Enhanced VariableRate Coder (EVRC) operation in addition to the standard 8k and 13k vocoding rating.3.3.4 Memory PartMemory part consisit of Flash Memory,SRAM and EEPROM.In the Flash Memory part included SRAM of U308 (8M x 2M bits), there are programs used for terminal operation.The programs can be changed through down loading after the assembling of terminals. On the SRAM(2Mbits), datagenerated during the terminal operation are stored temporarily. On EEPROM (128Kbits) which is U307, non-volatiledata such as unique numbers (ESN) of terminals are stored.3.3.5 Power Supply PartWhen the External DC (4.2V) is fed to the five regulators generated +3.0V. The generated voltages are used forMSM3000, IFT3000,IFR3000, audio codec, and other LOGIC parts. PWR ASIC is operated by the control signalSLEEP/ from MSM3000 and POWER_EN signal. Q606(DTC114EE) is turned on by ON_SW_SENSE/ and then, 'L' is outputted on ON_SW_SENSE/. MSM receives this signal and then, recognizes that the POWERkey has been pressed. During this time, MSM outputs PS_HOLD as 'H' and then, continues to activate D603 inorder to maintain power even if the PWR key is separated.3.3.6 Logic PartThe Logic part consists of internal CPU of MSM, RAM, ROM and EEPROM. The MSM3000 receives TCXO(=19.68Mz) from U7 and CHIPX8 clock signals from the IFR3000, and then controls the phone during the CDMAand the FM mode. The major components are as follows: CPU : ARM7TDMI coreFLASH MEMORY + SRAM: U308 (LRS13061)• FLASH ROM : 8Mbits • STATIC RAM : 2Mbits EEPROM : U307 (X84129S161-2.5) • 128Kbits EEPROMCPUARM7TDMI CMOS type 16-bit microprocessor is used and CPU controls all the circuitry. For the CPU clock,27MHz is used.FLASH ROM and SRAM
Flash ROM is used to store the terminal’s program. Using the down-loading program, the program can be changedeven after the terminal is fully assembled.SRAM is used to store the internal flag information, call processing data, and timer data.4.
