摘　　要：针对周期衰落信道下通信性能损失较大的问题，文章通过对周期衰落信道的仿真建模，利用Turbo编译码方案对其进行改善，在Matlab环境中对该方案的进行了仿真验证。结果表明，该方案对周期衰落条件下的通信性能有的改善。Aiming at the problem of large performance loss of communication in periodic fading chan- nels, this article describes the improving method of using periodic fading channel simulation modeling and Turbo encoding and decoding solution. It also makes simulation and verification of the solution under Matlab environment. The results show that the communication performance in periodic fading channel improves greatly.
