I'm looking for LDPC code Error correction which is implemented by professor David Mackey. I want to know is there any implementation of mentioned with matlab or no? in case if it's available where can i find it?

The decode phase is in http://www.mathworks.com/matlabcentral/fileexchange/28437-simulating-2-2-mimo-ldpc-base-band-systems; I guess it has the encoding as well.

Possibly en.pudn.com/downloads358/sourcecode/app/detail1557463_en.html which is MATLAB code for Low Density Parity Check .

Note: I would not say that I trust that site. You will likely also have to pay to get code from there.

You could also look to "Construction and Performance Evaluation of QC-LDPC Codes over Finite Fields" by Ihsan Ullah and Sohail Noor, here. The code is not in the PDF but they did implement in MATLAB and you might be able to get the source from them.

Thanks for your reply but unfortunately for this code: en.pudn.com/downloads358/sourcecode/app/detail1557463_en.html i downloaded already and it's not the one i"m looking for that and about this master theses the modulation they use is BPSK which is different form my proposed modulation and in this bock code i can not use this modulation Ihsan Ullah and Sohail Noor, and about Other resources: are with C implementation .

anyway thanks so much for your reply do you have any other sources which you can tell me ?
