Description: 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 channel.-this is 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 channel.

Description: 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 published journal papers with some additional improvements. In this code, we removed the parameter \lambda to reduce the number of free parameters. PBP estimator is distributed in the hope that is will be useful, but without any warranty. The codes have not been optimized, so the estimation speed may be slow. To use PBP estimator source code in your research, please cite our journal papers published in IEEE TCOM.

Description: 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 file extension " rec" ) noise seed awgn/bsc (noise mode, select here awgn) noise standard deviation Example: Gaussian encoded file a.enc channel transmission, transfer files received a.rec, which is a seed selection, select the noise standard deviation is 0.8
