摘要 针对LDPC码与RS码的串行级联结构,提出了一种基于Chase的联合迭代译码方法。软入软出的RS译码器与LDPC译码器之间经过多次信息传递,性能可以逼近最大似然译码。模拟结果显示:AWGN信道下这种基于Chase的RS码与LDPC码的联合迭代译码方案可以获得约0.5 dB的增益。 A joint iterative decoding algorithm for low density parity check codes with Reed-Solomon codes based on Chase algorithm is proposed.It allows to bridge the gap between error performance and maximum likelihood decoding.Simulation results for the scheme show that it may achieve about 0.5 dB gains over AWGN channel.
