MATLAB
- this an example of LDPC code in which after encoding i have added AWGN(Additive white Gaussian noise) and bsc(binary symmetric channel). then i hav performed decoding operation. one can easily devloped different BER vs Eb/N0 graph of different channe

PBP
- 用 LDPC 解码法，对原始信号通道的噪声进行评估，消去。具体原理可参照IEEE TCOM的论文。-Channel Noise Estimation or correlation estimation for distributed source coding Using Particle based Belief Propagation for LDPC decoding in AWGN and BSC models. This code is partially based on our
LDPC_Transmit
- LDPC码在高斯信道的传输 参数：编码文件名 接收文件名（文件扩展名为“rec”） 噪声种子 awgn/bsc(噪声方式，这里选择awgn) 噪声标准差 例：编码后文件a.enc通过高斯信道传输，收到传输文件a.rec，其中，种子选择为1，噪声标准差选择为0.8 -LDPC codes in a Gaussian channel transmission parameters: the encoded file name to receive the file name (the f
LDPC_Decode
- LDPC码的译码。参数如下： 校验矩阵文件名 接收文件名 译码结果文件名（文件扩展名为“dec”） awgn/bsc(噪声方式，和步骤6中的选择对应，这里选择awgn) 噪声标准差 prprp（表示迭代方式）迭代次数 例：对接收到文件a.rec迭代50次译码得到译码后文件a.dec： -Decoding LDPC codes. Parameters are as follows: file name check matrix decoding result of receiving
