中文摘要：

该文提出用Reed Solomon（RS）乘积码作为外码,卷积码作为内码的级联码方案并且内外码间用Congruential向量生成的交织图案对RS码符号进行重排列。对此级联码采用的迭代译码基于成员码的软译码算法。当迭代次数达到最大后,通过计算RS码的校正子,提出一种纠正残余错误的方法,进一步提高了系统的误比特性能。仿真结果表明,在AWGN信道中与迭代译码的级联RS/卷积码相比,当误比特率为1e-5时,新系统的编码增益大约有0.4dB。

英文摘要：

A concatenated coding scheme is proposed in this paper, which uses Reed-Solomon （RS） product code for outer code and convolutional code for inner code. The interleaving pattern, which is generated according to congruential sequence, is used to rearrange the symbols of RS product code .The iterative decoding of the concatenated coding scheme is based on the soft decoding of the component codes. When a given maximun number of iteration has been performed, a method is proposed to correct residual errors by computing the syndromes of RS codes. The simulation results show that coding gains up to 0.4 dB for a BER （Bit Error Rate） is of 1e-5 on the Gaussian channel comparison with concatenation RS/CC codes.
