Performance Evaluation of Turbo Codes in Mobile satellite channel

摘要

In this paper, analytical bound on the performance of turbo codes in mobile satellite shadowed Rician fading chanel is presented. And comarison with the performance on AWGN is discussed. The simulation results by computer on three different mobile satellite fading channel are also presenteed. In the meantime, the influence on turbo codes performance of different fading channel characteristic is highlighted. The roles of two main parameters for turbo codes-component code constraint length and the interleaver length-in mobile satellite shadowed fading channel are dicussed. Numerical results show that turbo ocdes can significantly improve the performance over shadowed fading channel.
