| 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RS1和RS2两路信号。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。 |
| 英文摘要: |
| 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. |
