The mpdecoder project provides an MATLAB class mpdecoder that allows doing message passing (MP) decoding of binary LDPC codes. The MATLAB class mpdecoder actually calls the C++ class MPDecoder through the MATLAB MEX interface, which ensures its high decoding speed.

A standalone MATLAB LDPC decoder mpdec is also provided to give a clear view of how the algorithm works. No C/C++ is involved.

Please start from the documentation file 'readme.txt'.

A MSVC++ project demonstrating the use of the C/C++ MPDecoder class is available here: https://github.com/alanzhou/MPDec
