  • Abstract
    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 10-4 is obtained.
