[matlabLDPCBSN

Description: LDPC码既低密度奇偶校验码(Low Density Parity Check Code,LDPC),它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码,不仅有逼近Shannon限的良好性能,而且译码复杂度较低, 结构灵活,是近年信道编码领域的研究热点,目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G) -LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.
