Analysis and improvement of the bit-flipping decoding algorithm for LDPC codes
LDPC比特翻转译码算法的分析与改进

According to the statistical decoding method,a new enlarged set of the low density check vectors was constructed by the linear combination among the vectors of the LDPC code's old check matrix.Combined with the analysis of the ParallelBit-Flipping(PBF) decoding algorithm,such as loop detection technique,a new hard-decision decoding algorithm was presented for LDPC codes.The simulation results show that our algorithm has small iterative numbers just like the PBF algorithm,and the decoding performance approaching the belief propagation algorithm.
