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

Matlab code for LDPC log-domain decoder in AWGN channel-Matlab code for LDPC log-domain decoder in AWGN channel BEC Channel and BSC channel

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
