    • Techniques to support low density parity check (LDPC) encoding and decoding are described. In an aspect, LDPC encoding and decoding of packets of varying sizes may be supported with a set of base parity check matrices of different dimensions and a set of lifting values of different powers of two. A base parity check matrix G of dimension m B ( En B ) may be used to encode a packet of k B =n B -m B information bits to obtain a codeword of n B code bits. This base parity check matrix may be "lifted" by a lifting value of L to obtain a lifted parity check matrix H of dimension Lm B ( ELn B ) . The lifted parity check matrix may be used to encode a packet of up to Lk B information bits to obtain a codeword of Ln B code bits. A wide range of packet sizes may be supported with the set of base parity check matrices and the set of lifting values.
    • 描述了支持低密度奇偶校验(LDPC)编码和解码的技术。 在一方面,可以用不同维度的一组基本奇偶校验矩阵和两个不同功率的提升值的集合来支持不同大小的分组的LDPC编码和解码。 尺寸为m B(En B)的基本奇偶校验矩阵G可以用于对k B = n B -m B信息比特的分组进行编码,以获得n个B比特的码字。 该基本奇偶校验矩阵可以通过升高值“L”升高,以获得尺寸Lm B(ELn B)的提升奇偶校验矩阵H. 提升的奇偶校验矩阵可以用于对高达Lk B信息比特的分组进行编码,以获得Ln B个码比特的码字。 基本奇偶校验矩阵和提升值集合可以支持大范围的分组大小。
