[Other resource] ldpcber DL : 0: This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

[Windows Develop] Matlab DL : 1: LDPC校验矩阵生成、高斯消去法编码、BP译码程序，可以作为自己编写LDPC编译码程序的参考。因为matlab代码效率不高，所以这个程序仿真起来比较慢.-LDPC check matrix generation, Gaussian elimination coding, BP decoding procedure can be used as its own procedures for the preparation of LDPC codec reference. Because matlab code efficiency is not high, so this process is relatively slow simulation together.

[Communication] LDPC DL : 0: The zip file contains 1. A 128x256 Regular (3,6) H matrix (if you need to simulate other codes, need to write your own code for generating those parity check matrices). The file 128x256regular_v6.mat is for those using Matlab 6.5. 2. Files for LDPC code simulation over the AWGN channel. 3. Matlab-based and C-based (C-mex file)implementation of the LDPC decoder. The main simulation script contains the commands for the use of both decoders (there are 2 C-based decoders and one Matlab based). The commands for the decoder that are going to be used need to "uncommented", and those for the other decoder need to be "commented". 3a. To compile the C-mex file, need to install a C compiler (I have used Miscosoft Visual C++ 6.0). Then have to go to the Matlab command window and do ">>mex -setup" (then go through the steps of selecting the desired compiler). -The zip file contains 1.
