`
`2. Key Features
`
`2.1 OCQPSKlOrthogonal Complex QPSK.)
`
`OCQPSK (Orthogonal Complex QPSK) is a modulation method that reduces the peak-to-average power
`ratio of the TTA proposal I reverse link signal. Since the peak-lo—average power ratio is directly related to
`the cost and efficiency of the power amplifier (PA), this is a very important issue for the hand-held
`terminal. Generally speaking, Code Division Multiple Access (CDMA) signals requires a strict linearity of
`power amplifiers. Main features of IM‘T-ZQOO system include high data rate service that is achievable by
`employing mold—code, or variable spreading factor. Multi code based modulation usually increases the
`peak—ro-average power ratio, which in turn increases the non-linearity level and adjacent channel power by
`high frequency characteristic.
`
`Figure 2.14 ShDWS the structure of 5 channel OCQPSK. For 3-chanoel case, one traffic channel is used to
`guarantee the transmission of up to lZSKbps in SMHa system. For the transmission of up to 384Kbps in
`SMHZ system, 2 more traffic channels are assigned. Orthogonal complex signal Wu+jW, serves as a

`rotator in complex space which avoids zero crossing by limiting : 90° rotation. W9 and W1 represent
`Walsh 0 code and Walsh 1 code respectively. After this rotation, the complex signal is spread by a single
`pseudo—noise (PN) code. The. rotatitm of the input complex signai significantly reduces the peak-to-

`2.2 TSTDCITime Switched Transmit Diversity)
`
`To improve the demodulation performance for the forward link, “ETA synchronous EMT-2000 base station
`adopts transmission diversity scheme in the forward link transmission- Adopting the transmission diversity
`means that more than one transmission antenna might be used for the forward link signal transmission.
`Because of the orthogonal property in the forward link, the transmission diversity scheme that is adopted
`should keep tho orthogonal transmission property. To keep the orthogonaiity, the transmitted signal from each
`antenna should be orthogonal to each other. To achieve this orthogonality, 'I'I‘A synchronous MTJODO base
`station transmits the modulated signal through transmission antennas with time switching and noneoverlapping
`manner.
`'
`'
`
`2.2.1 Time Switched Transmission Diversity
`
`Time switched transmission diversity {'I‘STD) which is orthogonal due to time separation is used for Trafiic
`and Signaling Channel (except for Pilot Channel). It is implemented by transmitting signals offomard link
`channels for the some user by time switching PN spread bits into two (or more) data streams. These scrambled
`bit Streams are transmitted through two (or more) separate antennas.
`
`The Walsh spread sequences are masked by a quadrature pseodmnoise (PM) sequence, which is the same for
`all the users of the some sectors. After EN masking, the modulated signal
`is tie-multiplexed into multiple
`signal stream with period of M times of Walsh code length and transmitted to each antenna. Thus,
`orthogonality is maintained between the two output streams due to the time separation between the signaI
`streams. By splitting the modulated signal into two or more separate data streams, the effective number of
`spreading codes per user is the same as the case without transmission diversity.
`Assuming that without transmission diversity, Walsh code Wk of length 2'" is assigned for a certain data rate,
`With time switched transmission diversity, the scrambled bit stream is split into two using time switching, so
`the scrambled bit rate of each antenna is samé of the original rate. Thus length of Walsh code Wk is not
`changed.
`
`The block diagram of the forward link Traffic and Signaling Channel with transmission diversity is given in
`Figure 2.2.1-1.

`2.2.1.1 Switching Methodology
`
`The scrambled hits are time separated with period ofM times of Walsh code length for transmission diversity
`and transmitted to each antenna. In this case, the switching methodologies of regular and scrambling switching
`are possible implementation of TS’I’D. The selection of switching methodology is determined by switching
`controller. The switching methodology for Signaling Channel. (Sync and Paging Channel) must be same in all
`BS. But for Traffic Channel, it's not necessary.
`
`2.11.1.1 Regular Switching
`
`The regular switching methodology split the scrambled bits to switching frame with period of M times of
`Walsh code length, then transmit the switching from: to each antenna sequentially, In Figure 2.11.1.151,
`conceptual drawing of the regular switching transmission is shown for 2 antennas transmission example’ Due
`to the synchronous operation of ETA synchronous MAT-2000 system, all the mobile stations and base stations
`can detect the appropriate time: slot for modulation and demodulation.

`2.2.2 Pilot signal generation. -
`
`To achieve the coherent demodulation with the transmission diversity, pilot signal should be transmittad along
`each transmission antenna.
`
`For the Pilot Channel of 'TTA Synchronous ZMTQDOD system forward link, orthogonal code transmission
`diversity (OTB) loosed. The formation of the pilot signal is shown in Figure 2.2.2—1 for the 2 antennas
`transmission diversity example. It is implemented by transmitting signals of forward link channels for tho same
`user by splitting coded bits into two (or more) data streams. These codcd bit streams are transmitted through
`two (or more) separate antennas after being spread by different Walsh codes orthogonal to each other for each
`antenna The Spread sequenccs are scrambled by a quadrature pseudo-noise (PM) sequence, which is the some
`for all the users of the some sectors. Thus, orthogonality is maintained betwaen the two output streams, and

`
`In the case of two transmission antennas, one preferred method of assigning Walsh codes to diffamn: antennas
`is as follows. Assuming that without transmission diversity, Walsh code Wk of Tcngth 2'“ is assigned Em a
`certain data rate, wilh transmission diversity, the coded bit stream is split into two and the coded bit rate of
`each antenna is reduced in half of the originai rate. As a result, each of the bit streams is spread by Walsh
`00ch of length 2"“. We can simply construct two such codes from Wk by forming {Wt Wk} and [Wk 4W}-
`A block diagram of such an Piiot Channel transmiuer is given in Figure 2.2.24. The length of Wk is defined
`in this section as the Walsh coda Icnglh.

`23 Fast Forward Power Controi
`
`To meet the requirement of the system pnrfumancc, the base station transmit power is adjusted by the: {inward
`link power control. The mobile simian should estimate the received powcr control bit that is seni for the
`reverse link power CDBiTOi. To guarantee the pnwer estimation zicxmracgri the power of the power control bits is
`adjusied by increasing their amplitude level or their time duration. According to simulation results, their
`power level has bcen detmnincd as 3 dB higher than the 9.6 Kbps voice traffic. Accordingly, the mobile
`station generaics the power comm] command through the reversa link.
`
`FEC rate can be changed to provide more gain to MS under bad channel environment, larger path lass, severe
`interfcrencc,
`larger TX power. For cxamplc, suppose mat BS and MS cemmunicatc with a

`The proposed system may employ halfileogth transmission to enhance inteEfrequency handofi capability for
`voice service. This provides more efficient inter-frequency handoff to the proposed system with minimal
`per-romance loss.
`
`In forward link, the transmission length of Traffic Channel frame is shortened by half in order for mobile
`station to search other fiequeneies with a single RF receiver during the other half frame interval. Figure 2.6.2-
`1 illustrates half-length transmission and nouns! transmission. Shortened period shall include at least one
`,Sequence of repeated modulation symbols. For the frame that has less than two repeated sequences, the full
`rate frame in forward link, rate limitation may be used. Perfonnanoe reduction caused by reduced repetition is
`compensated by inmeasing modulation symbol energy. For half-length transmission frame. modulation symbol
`energy is transmitted with energy not less than two times modulation symbol energy without hair—length
`transmission. Relative modulation symbol energy to that of full rate frame is shown in Table 2.6.2—1.
`
`Femoral Signaling Channel is not transmitted during the non~transmissioo interval generated by haif—lengih
`transmission.

`Successive haif-length transmission may be used for the duration. of intensive frequency scanning. Each
`starting position of transmitted modulation symbols during successive transmission limitation is alternately
`changed to the front part or the rear part of each frame as shown in Figure 2.6.24. This allows minimizing
`guard time overhead for frequency switching.

`
`These two Piiot Channels are unmodulated sproad spactrum signals (Figure 23—3) that is used for timing and

`shared between ail mobiles in the cell and is used to obtain fast acquisition of new multipaths and channcl
