摘要 针对紫外光通信信道的特殊性,采用当前优异的信道编码技术Turbo码进行编码,利用Matlab软件,在瑞利衰落信道条件下,仿真分析不同Turbo码译码算法对译码性能的影响,发现在相同条件下,Log-MAP算法性能好于SOVA算法。这为Turbo码在紫外光通信系统中的应用提供了一定的理论基础。 Turbo code encoding,the current outstanding channel coding is adopted out of consideration of the particularity of UV communication channel. The different Turbo code decoding algorithm is simulated by using Matlab in Rayleigh fading channel conditions and analyzed for the effects on decoding performance. It is found that Log - MAP algorithm performance is better than SOVA algorithm under the same condition. It provides a theoretical basis for the application of Turbo code in UV communication system in the future.
