statistical coding

According to the statistical decoding method,a new enlarged set of the low density check vectors was constructed by the linear combination among the vectors of the LDPC code s old check matrix.

利用统计译码思想由LDPC(Low Density Parity Check)码校验矩阵通过矢量的线性组合构造出一个新的低密度校验矢量集合,并结合LDPC码并行比特翻转译码算法的环检测等特点的分析,提出了一种新的硬判决译码方案。
