基於matlab編寫LDPC之編碼及BF、SPA、Log-SPA等演算法及系統錯誤率計算-The preparation of LDPC codes based on matlab and BF, SPA, Log-SPA and other algorithms and system error rate

本程序包含LDPC码的BF、WBF、IMWBF等不同译码算法的时间复杂度以及性能比较。-This program is about different decoding algorithm of LDPC codes including time complexity and performance comparison of BF, WBF, IMWBF .

ldpc码的比特反转译码算法利用C语言实现，虽然简单但比较完整(The bit inversion decoding algorithm of LDPC code is implemented in C language, which is simple but complete.)
