Abstract

This paper outlines a work on a design of parity check matrix for Irregular LDPC codes. The design is based on the adjustment of the modified array LDPC codes and interleave-modified array LDPC codes. The code rate of 0.930 is obtained. LDPC Codes based on this design suits the short and medium block length.
