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码是Low Density Parity-check Codes的缩写，一个长为N的LDPC码由它的校验矩阵H来定义，该矩阵的特点是其中的元素0特别多，1特别少——即所谓的“低密度”。一个参数为（N，i，j）的H表示该矩阵中每列有i个1，每行有j个1，矩阵大小为N×K，N代表码字长度，K代表校验子的个数。
-LDPC code is the ab. of Low Density Parity-check Codes. A Length N LDPC is defined by its H matrix. The matrix has many zeros and few ones. which called "low density". An H matrix has a parameter as (N,i,j) express that it is the matrix which has i s 1 in each column ,j s one in each row, the size of the matrix is N*K,the N is the code word length ,k is the number of the checks.

Description: There is an example of how to use the LDPC encode/decode with AWGN
channel model in files .\ldpc_decode.m and .\GFq\ldpc_decode.m.
There are a few parity check matrices available in the code but
you can use other matrices provided you have enough memory to load
them. I suggest checking out matrices in Alist format available on
David MacKay s web site.You will need to have access to a MEX compiler
to be able to use a few functions written in C.
