C program to calculate the BER performance of BPSK modulation in an AWGN channel. The program takes the file "BPSK" containing voltage levels and passes it in an AWGN channel with a given SNR. The received message is then Hard decision decoded and the bit error rate is calculated. The BER over different SNR is calculated. THe output values can be used to draw a BER vs SNR(dB) curve.

中文RFC文件，无需翻译，对学习很有帮助！

文件中包括的随机数发生器，将 Alist 矩阵转换成一般矩阵，做的 enc 部分。此 enc 方法只侧重于下三角矩阵，它可以变得更容易得到 enc 消息。希望此文件可以帮助您很多有关如何进行编码与低三角奇偶校验矩阵的 LDPC 码。我也写一个 matlab 文件来检测代码 c 是正确还是不。
