[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).

[Program doc] boundsonLDPCandLDGM DL : 0: The paper is about bounds for LDPC and LDGM codes under MAP. A new method for analyzing low density parity check (LDPC) codes and low density generator matrix (LDGM) codes under bit maximum a posteriori probability (MAP) decoding is introduced. The method is based on a rigorous approach to spin glasses developed by Francesco Guerra. It allows to construct lower bounds on the entropy of the transmitted message conditional to the received one. Based on heuristic statistical mechanics calculations, we conjecture such bounds to be tight. The result holds for standard irregular ensembles when used over binary input output symmetric channels. The method is first developed for Tanner graph ensembles with Poisson left degree distribution. It is then generalized to ‘multi-Poisson’ graphs, and, by a completion procedure, to arbitrary degree distribution.

[Program doc] these DL : 0: 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 codes, since they enable to get as close as a fraction of a dB the Shannon limit.
