40、General In the following, a separation between the data modulation and the spreading modulation has been made. The data modulation for 3.84Mcps TDD (including 3.84 Mcps MBSFN IMB) and 7.68Mcps TDD is defined in clause 5 Data modulation for the 3.84 Mcps and 7.68Mcps options, the data modulation for
41、1.28Mcps TDD is defined in clause 5A Data modulation for the 1.28 Mcps option and the spreading modulation in clause 6 Spreading modulation. Table 1 shows the basic modulation parameters for the 7.68Mcps, 3.84Mcps (including 3.84 Mcps MBSFN IMB) and 1.28Mcps TDD options. Table 1: Basic modulation pa

The PSC, Cp, is defined as
44、 Cp= where and the left most index corresponds to the chip transmitted first in time. The 12 secondary synchronization codes, C0, C1, C3, C4, C5, C6, C8,C10,C12, C13, C14,C15 are complex valued with identical real and imaginary components, and are constructed from the position wise multiplication of
45、 a Hadamard sequence and a sequence z, defined as z = , where b = and x1, x2, x3, , x16 are the same as in the definition of the sequence a above. The Hadamard sequences are obtained as the rows in a matrix H8constructed recursively by: The rows are numbered from the top starting with row 0 (the all
46、 ones sequence). Denote the n:th Hadamard sequence hnas a row of H8numbered from the top, n = 0, 1, 2, , 255,in the sequel. , where m = (16i) and the leftmost chip in the sequence corresponds to the chip transmitted first in time. 7.2 Code Allocation Three secondary SCH codes are QPSK modulated and
47、transmitted in parallel with the primary synchronization code. The QPSK modulation carries the following information: - the code group that the base station belongs to (32 code groups:5 bits; Cases 1, 2); - the position of the frame within an interleaving period of 20 msec (2 frames:1 bit, Cases 1,
48、2); - the position of the SCH slot(s) within the frame (2 SCH slots:1 bit, Case 2). The modulated secondary SCH codes are also constructed such that their cyclic-shifts are unique, i.e. a non-zero cyclic shift less than 2 (Case 1) and 4 (Case 2) of any of the sequences is not equivalent to some cycl
49、ic shift of any other of the sequences. Also, a non-zero cyclic shift less than 2 (Case 1) and 4 (Case 2) of any of the sequences is not equivalent to itself with any other cyclic shift less than 8. The secondary synchronization codes are partitioned into two code sets for Case 1 and four code sets for Case 2. The set is used to provide the following information: Case 1: Table 2: Code Set Allocation for Case 1 Code Set Code Group 1 0-152 16-31The code group and frame position information is provided by modulati
