32、n+2 TSn+3 TSn+4 TSn+5 TSn+6 The Primary slot for multi-rate operation is defined as the first time slot transmitted in a contiguous group of 3 slots The Secondary slot is defined as the one or two slots following the Primary fiist transmitted slot within the same contiguous group of 3 slots. Determi

33、nation of the Primary slot and Secondary slot is given by the Assigned Time Slot information element. For d4 DQPSK the Bit Positions (BP) for DTX Low Truncated Burst Slots are numbered sequentially from 1 to 68. The Bit Positions (BP) of forward and other reverse time slots are numbered sequentially

34、 from 1 to 324. In the forward time slot, the fiist transmitted bit of the SYNC field has BP = 1 and the last transmitted bit of the CDL field has BP = 324. In the reverse time slot, the fiist transmitted bit of the G field has BP = 1. Interpretation of the above fields is as follows: G- R- Pn - F1,

39、 R: 3 symbol length Ramp time. S: 14 symbol length Sync Word; The mobile station uses its assigned sync word. D: 6 symbol length CDVCC; The mobile station uses its assigned DVCC. G2: 22 Symbol length guard time. Note that the first 3 symbols of G2 consist of RAMP. The fields V,W,X,Y contain bits as

40、follows: v= O000 w= 00000000 x = 000000000000 Y= 0000000000000000 The above format allows determination by the base station of Timing Alignment after detection of any 2 or more sync words of the Shortened Burst. This is because the symbol interval between any two sync words in the above format is un

41、ique to the 2 sync words detected. Determination of the number of symbols between two detected sync words uniquely defines the location of the detected sync words within the received Shortened Burst. Frame Length The mobile station shall derive timing for the transmit symbol and TDMA frame and slot

42、clocks from a common source which shall track the base station symbol rate as perceived at the mobile station receiver. The frequency tracking shall be maintained over all specified operating conditions. The frame length on each digital TDMA RF channel shall be 40 milliseconds. Each frame shall cons

43、ist of six equally sized time slots (1-6), exactly 162 symbols in length. Each full-rate traffic channel shall utilize two equally spaced time slots of the frame (1 two di-bit symbols corresponding to adjacent signal phases differ only in a single bit. Since most probable errors due to noise result

44、in the erroneous selection of an adjacent phase, most di-bit symbol errors contain only a single bit error. Note also, the rotation by .n/4 of the basic QPSK constellation for odd (denoted O) and even (denoted O) symbols. Figure 14 Phase Constellation I The information is differentially encoded; sym

45、bols are transmitted as changes in phase rather than absolute phases. A block diagram of the differential encoder is shown in Figure 15. The binary data stream entering the modulator, bm, is converted by a serial-to- I parallel converter into two separate binary streams (Xk) and (Yk). Starting from

46、bit 1 in time of stream bm, all odd numbered bits form stream xk and all even numbered bits form stream Yk. 19 TINEIA-136-131-C m b O Figure 45 Differential Encoder Differential phase encod i ng Serial -to- parallel Qk converter k Xk 1 O O 1 4 Yk AO -3.n 4 3.n 4 - 1 - 1 O O n - 4 -n - 4 5 6 The digi

The phase change A is determined according to the following table: The s

48、ignals Ik,Qk at the output of the differential phase encoding block can take one of five values, O, I 1, f - resulting in the constellation shown in Figure 1 il. 1 Jz 20 TINEIA-136-131-C 5 6 I 8 Impulses Ik, Qk are applied to the inputs of the I two three-bit symbols corresponding to adjacent signal phases differ only in a single bit. Since most probable errors due to noise result in the erroneous selection of an adjacent phase, most three-bit symbol errors contain only a single bit error. Also, note that phase transitions between any two symbol phases in Figure 17 are possible. 22
