In this paper, we propose a effective grouping method for the Group Shuffled BP decoding algorithm using the irregular LDPC codes according to the structure of a Tanner graph and the degree distribution of the
codes which can accelerate the convergence speed and in result reduce the decoding delay. We show simulation results which indicate that the decoding performance of the proposed grouping method is better than those of the conventional grouping method. |
