奇偶校验位的计算采用稀疏LU分解，利用H的稀疏矩阵特性，LDPC码的译码采用迭代置信传播或和积算法（SPA）。介绍了SPA解码器的四种版本。
Parity check bits is computed using sparse LU decomposition, utilizing sparse matrix properties of H. LDPC code decoding is done using iterative belief propagation or sum-product algorithm (SPA). Four versions of SPA decoder are presented.
