    摘要: A Synchronization Channel (SCH) transmission method includes generating a Primary SCH (P-SCH) sequence according to supplementary information. The supplementary information includes at least one of Base Station (BS) type information, Fast Fourier Transform (FFT) size information, BandWidth (BW) information, group information, sector information, and carrier type information. The method also includes modulating the P-SCH sequence and mapping the modulated P-SCH sequence to subcarriers within a predefined subcarrier set. The subcarriers are included in the subcarrier set being spaced one subcarrier interval apart. The method further includes generating a P-SCH symbol by Orthogonal Frequency Division Multiplexing (OFDM)-modulating the P-SCH sequence mapped to the subcarriers, and transmitting the P-SCH symbol.

The first parity check matrix is a parity check matrix supporting the number of information vector square matrix columns determined by using the length of the information vector and the value L from the p parity check matrixes, and the value L is determined by using p and the length of the information vector.
