RS码的分布式编码协作系统方案设计

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。

The Scheme Design of Distributed Cooperative System of RS Code

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.
