Description: Software for Low Density Parity Check Codes Radford M. Neal Version of 2006-02-08. 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 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.

Description: LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G)
-LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.

Description: Low-density parity-check (LDPC) codes are a class of linear block LDPC
codes. The name comes from the characteristic of their parity-check
matrix which contains only a few 1’s in comparison to the amount of
0’s. Their main advantage is that they provide a performance which
is very close to the capacity for a lot of different channels and linear
time complex algorithms for decoding. Furthermore are they suited
for implementations that make heavy use of parallelism.
They were first introduced by Gallager in his PhD thesis in 1960. Gallager,
But due to the computational effort in implementing coder and en- 1960
coder for such codes and the introduction of Reed-Solomon codes,
they were mostly ignored until about ten years ago
