ConstructQCLDPCgirth4
- Construct the short length of QC LDPC codes without girth 4 and girth 6
Girth-twelveQC-LDPC
- 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).
constructsgirth-sixQC-LDPC
- constructs girth-six column-weight three QC-LDPC codes
Girth-eightQC-LDPC
- The algorith divides rows in to four equal groups. The rows are then used to from a distance graph which is then transformed into a matrix. girth of eight is maintained by avoiding six-cycles in the graph construction
Girth-8QCL-PDC
- 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
girth4_count
