| 摘 要： | 针对大气激光信道对光信号衰减极大的特性,提出了一种用Simulink构建的Turbo码系统仿真模型,分别与未采用信道编码和采用卷积编码方案的仿真系统进行了误码率(BER)性能对比,结果显示出了Turbo码在实现低误码率的大气激光信息传输中的优越性,为Turbo码在大气激光通信系统中的应用提供了理论基础.

| Abstract: | In view of the severe attenuation of optical signals in atmospheric channels,we propose a simulation model for Turbo code system constructed by using Simulink and compare its BER performance with those of the simulation systems without using the channel coding scheme and with the convolutional coding scheme.The results demonstrate the superiorities of Turbo code in wireless optical transmissions in terms of low BER and provide a theoretical basis for its applications in these systems. |
