The performance of a combination of the irregular low-density parity-check (LDPC) codes and the belief-propagation (BP) decoding algorithm strongly depends on a structure of their parity-check matrixes, and some of the codes exhibit bad performance.In this paper, we propose methods for constructing structured irregular LDPC codes which effectively facilitate for the BP decoding algorithm. We also develop methods for effective updating rules according to the bit node positions for the Shuffled BP decoding algorithm. We also show by simulation results that the decoding performances of the proposed irregular LDPC codes are better than those of the conventional ones. |
