摘　　要：为了降低RS码分布式编码协作系统的误码率,在深入研究RS编译码算法的基础上,提出了合并-智能联合译码算法。该算法在智能译码算法中增加一个合并器,以充分利用RS_1和RS_2两路信号。仿真实验表明,当误比特率为10^(-3)时,与简单联合译码算法相比,采用合并-智能联合译码算法的编码协作系统能获得3.7 dB的增益;在使用自适应系数的情况下,合并-智能联合译码算法能够使编码协作系统获得最佳的性能。因此,合并-智能联合译码算法可以有效提高RS码编码协作系统的性能。In order to reduce the bit error rate of the RS code distributed coding cooperative system,based on the in-depth study of the RS codec algorithm,a merge-intelligent joint decoding algorithm is proposed.In this algorithm,a combiner is added to the intelligent decoding algorithm to make full use of the two signals(RS1 and RS2).When the bit error rate is 10-3,compared with the simple joint decoding algorithm,the coding cooperation system using the combined-intelligent joint decoding algorithm can obtain a gain of 3.7 dB.In the case of using adaptive coefficients,the merge-intelligent joint decoding algorithm can make the coding cooperative system get the best performance.Therefore,merge-Intelligent joint decoding algorithm can effectively improve the performance of RS coding collaboration system.
