摘要
结合大气信道的特点和Turbo码的基本编译码结构,构建了基于Turbo码的大气激光通信系统Simulink仿真模型。在此基础上,针对大气湍流的光强闪烁效应,运用MATLAB软件,采用Log-MAP译码算法,仿真分析了交织器方案对Turbo码大气激光通信系统性能的影响,得到利于Turbo码在大气激光通信系统中获得实际引用的一些结论。
Combining the characteristics of atmospheric channel with the structures of Turbo encoding and decoding, the Simulink model of atmospheric optical communication system based on Turbo codes was created. Basing on it, we use the Simulink in MATLAB , the system performance effects of different interleaver schemes of Turbo codes were simulated and compared by adopting Log-MAP arithmetic. The conclusions which are very valuable for applying the Turbo codes to the real atmospheric optical communication systems are given.
