This paper outlines the work on another design of a parity check matrix for Irregular LDPC codes. The design is based on the pattern of Modified Array and Interleaved Modified Array LDPC codes. The application of matrix transposition Quasi-cyclic shifting has resulted in the reduction of 1's. The designed matrix is suitable for codes with short and medium block lengths. The code rate of 0.56 at the BER of 10-4is obtained.
