Applied quasi-cyclic LDPC codes from doubly-extended RS code and cyclic MDS code

Based on doubly-extended RS codes and cyclic MDS codes,two construction schemes were proposed for ap-plied quasi-cyclic LDPC codes whose Tanner graph is free of 4-cycles.In the first approach,all the nonzero codewords within a doubly-extended RS code were employed,and hence provided more flexible pa...
