研究了采用Turbo码技术的抗衰落性能,首先分析了Turbo码在卫星移动遮蔽Rician衰落信道下的误差纠错性能限,然后通过计算机仿真模拟了三种不同的卫星移动衰落信道下Turbo码的性能,研究了不同衰落信道特性对Turbo码性能的影响情况,同时还讨论了在衰落信道下Turbo码的子码约束长度和交织器长度两个主要参数对性能的影响情况。

In this paper, theoretical analysis of error rate performance about Turbocode on Mobile satellite shadowed Rician fading channel is presented. And comparison with the performance on AWGN is discussed. The simulation results by computer on three different mobile satellite fading channel is also presented. The influence on Turbocode performance of different fading channel characteristic is highlighted. In the meantime, the roles of two Turbocode main parametersconstitute code constraint length and the interleaver lengthon Mobile satellite shadowed fading channel is discussed.
