摘要 在分析传统LDPC编码方式的基础上,提出一种基于本原多项式实现LDPC编码的新方法。根据特定LDPC码长选择合适的本原多项式作为子矩阵,对子矩阵进行行列分解、组合,最终构建LDPC码校验矩阵H。仿真实验结果和工程应用证明:新算法构建的LDPC码在恶劣的通信环境下,误码率、误帧率优于传统Mackay-LDPC码,具有较好的性能。 A new LDPC(Low Density Parity Check) code constructed by primitive polynomial is proposed based on analysis of traditional LDPC. The appropriate primitive polynomials are selected as the sub - matrixes by the length of the specific LDPC. Then the matrixes are decomposed and combined to construct the check matrix. The simulation and engineering applications prove that the performance of LDPC code constructed by proposed algorithm is better than that of Mackay - LDPC. The BER( Bit Error Rate) and FER( Frame Error Rate) are both lower in the bad communication environment.
