Qclpdc

The program constructs girth-twelve column-weight QC-LPDC codes. The rate can be changed by changing k(row-weight), size is changed by varying m(sub-matrix size). The program/algorithm does not guarantee to get girth twelve code. It guarantees girth of eight. One may need to run the programs many... Platforms: Matlab

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. Platforms: Matlab

The program constructs qc-lpdc codes given size of sub-mnatrix(m), girth(g1), row (k) and column(j) weights. It uses a serch algorith that might not find a code gvien the above parameters. The program is also given a Base-Matrix. Platforms: Matlab
