Abstract
4-ary LDPC ( Low-Density Parity-Check) Code has better performance of resistance to burst errors. To improve performance and reduce the complexity of algorithm,this paper mainly about the research of 4-ary LDPC codes with a short code length based on binary LDPC codes.Based on the layer belief propagation,this paper proposes serial decoding algorithm based on the accuracy of check node. Under non-binary AWGN channel, in terms of a short code length, simulation results show that the performance of improved serial decoding algorithm is better than layer belief propagation,it can achieve 0.25dB performance gain at the symbol error rate of 10-2 .关键词
