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. Error Correction Codes (ECC) is one of many tools made available for achieving consistent data transmission. Low-Density Parity-Check codes (LDPC), as ones of many kinds, are also linear block codes that have been studied vastly in this decade.
