Description: The BCJR algorithm is an algorithm for maximum a posteriori decoding of error correcting codes defined on trellises (principally convolutional codes). The algorithm is named after its inventors: Bahl, Cocke, Jelinek and Raviv.[1] This algorithm is critical to modern iteratively-decoded error-correcting codes including turbo codes and low-density parity-check codes.

Description: The Low-Density Parity-Check codes are among the most powerful forward error correcting
codes, since they enable to get as close as a fraction of a dB the Shannon limit.
This astonishing performance combined with their relatively simple decoding algorithm
make these codes very attractive for the next digital transmission system generations. It
is already the case for the next digital satellite broadcasting standard (DVB-S2), where
an irregular LDPC code has been chosen to protect the downlink information.-The Low-Density Parity-Check codes are among the most powerful forward error correcting

Description: C语言实现的LDPC（Low Density Parity Check Codes）通信仿真代码(Software for Low Density Parity Check Codes
Version of 2012-02-11.
This collection of programs and modules, written in C, is intended to support research and education concerning Low Density Parity Check (LDPC) codes. (Note, however, that the copyright notice no longer restricts use to these purposes). These error-correcting codes were invented by Robert Gallager in the early 1960's, and re-invented and shown to have very good performance by David MacKay and myself in the mid-1990's. The decoding algorithm for LDPC codes is related to that used for Turbo codes, and to probabilistic inference methods used in other fields. Variations on LDPC and Turbo codes are currently the best practical codes known, in terms of their ability to transmit data at rates approaching channel capacity with very low error probability.)
