摘要 针对LDPC码的迭代编码算法提出了一种具有下三角结构的非规则LDPC码校验矩阵的构造方法。仿真结果表明:在MSK调制及BPSK调制情况下,根据本文提出的构造方法所构造出的LDPC码不仅具有线性的编码复杂度及矩阵构造和存储简单的优点,同时具有较强的纠错能力。 On the basis of the iterative encoding algorithm of low density parity check(LDPC) codes,a construction method of irregular LDPC codes checking matrix in lower triangle structure was presented.Simulation results indicate that the performance of the proposed method in both MSK modulation and BPSK modulation can possess linear operation complexity,simple matrix structure,easy storage property,and strong capacity for error correction.
