Low density parity check code being the most powerful Error correcting code with performance near to Shannon limit is studied and simulated in this paper. Because of its performance it is used in Digital Video Broadcasting Satellite for Second Generation (DVBS2).In this paper, LDPC encoding algorithm named “Irregular repeat accumulated code” has been illustrated in detail. There are several algorithms existing for the decoding of the LDPC decoder. Among them here, two decoding algorithm named “Turbo decoding message passing Algorithm” and “Two phase message passing algorithm” has been illustrated and simulated in MATLAB. The results comparing these two decoding algorithms and different iterations have been presented in this paper.
