North Carolina Area Codes

The program contructs column-weight three girth-eight QC-LPDC codes given row-weight and sub-matrix size. row-weights and sub-matrices sizes are variable.

it encodes and decodes binary msg using hamming codes and detect errors, correct single error.

The set of MATLAB codes are what I wrote for my Data Communications homework. They show a typical implementation of a (7,4) Hamming code. 'Read the how to run.txt' for instructions on how to use the codes
