Abstract :
Low density parity check (LDPC) codes are one of the best error correcting codes known to approach the Shannon limit. This paper examines the impact of different rates and code lengths of Log Belief Propagation LDPC algorithm on the performance of digital video broadcasting-satellite-second generation (DVB-S2) on both Additive white Gaussian Noise (AWGN) channel and Rayleigh fading channel, it also examines low complexity LDPC algorithm which is minimum sum LDPC algorithm for DVB-S2 with different numbers of iterations and simulating it on both channels using matlab targeting to chose the appropriate algorithm for the architecture of DVB-S2 to be implemented hierarchically on semi-parallel LDPC design Field Programmable Gate Array.
