  • LDPC编码算法研究及其FPGA实现.rar

    LDPC(Low Density Parity Check)码是一类可以用非常稀疏的校验矩阵或二分图定义的线性分组纠错码,最初由Gallager发现,故亦称Gallager码.它和著名Turbo码相似,具有逼近香农限的性能,几乎适用于所有信道,因此成为近年来信道编码界研究的热点。 LDPC码的奇偶校验矩阵呈现稀疏性,其译码复杂度与码长成线性关系,克服了分 ...

  • There is an example of how to use the LDPC encode/decode with AWGN channel model in files .ldpc_de

    There is an example of how to use the LDPC encode/decode with AWGN channel model in files .\ldpc_decode.m and .\GFq\ldpc_decode.m. There are a few parity check matrices available in the code but you can use other matrices provided you have enough memory to load them. I suggest checking out matri ...
