有关LDPC码的基础知识，对于初学者有很好的帮助。里面包括置信传播译码算法以及对比图-LDPC codes based on knowledge, there is a good help for beginners. Which includes belief propagation decoding algorithm and comparison chart

Low-Density Parity-Check (LDPC) codes have gained lots of popularity due to their capacity achieving/approaching property. This work studies the iterative decoding also known as message-passing algorithms applied to LDPC codes. Belief propagation
