| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The combination of the Low-Density Parity-Check (LDPC) codes and the iterative decoding algorithm has shown high performance. A well-known iterative decoding algorithm, the Belief-Propagation (BP) decoding algorithm, decodes all symbols in parallel at each iteration. An improved BP decoding algorithm, the Shuffled BP decoding algorithm, decodes each symbol in serial at each iteration. To reduce the decoding delay of the Shuffled BP decoding algorithm, the Group Shuffled BP decoding algorithm divides all symbols into some number of groups. It processes each group in serial, and all symbols in a same group, in parallel. While it generates the groups in symbol positions order, In this paper we propose a new symbol grouping algorithm which generates the groups with respect to the structure of a graph in Tanner graph of the codes. We show simulation results which indicate that the decoding performance of the proposed method is superior to those of the Shuffled BP decoding algorithm and the Group Shuffled BP decoding algorithm. |
