通过对软判决、低密度奇偶校验码(LDPC)编码进行了研究,构造了更高编码增益的LDPC与里德-索罗门码(RS)级联码.仿真结果表明,RS和软判决LDPC级联的编码方式,能够在RS(255,239)的基础之上提高4.5dB的编码增益.%The soft-decision based low density parity check (LDPC) codes are stdudied, and a concatenatedLDPC and Reed-Solomon (RS) codes is proposed. The simulation results indicate that the proposed code mayachieve more coding gains than RS(255,239)'s about 4.5dB.
