摘要

为了减轻卫星无线信道中多径衰落的有害影响，前向纠错(FEC)技术在过去的几十年里得到了广泛的应用。里德-所罗门(RS)编码是当前经历深度衰落的卫星系统的首选fec之一。对于卫星信道，多径分量通常也存在一条直接路径，衰落引起的衰减可以用统计量来表征。本文提出了一种基于RS码的双相移键控(BPSK)调制的误码率的简化表达式。通过MATLAB仿真验证了分析得到的误码率值。还包括对仿真代码开发的详细讨论。

A simplified analytical and simulation framework for evaluating BER of RS coded digital signal in Rician fading channels

In order to mitigate the deleterious effects of multipath fading in satellite wireless channels, forward error correction (FEC) techniques had been used for past several decades. Reed-Solomon (RS) coding is one of the preferred FECs for current satellite systems that experience deep fading. For satellite channels, often a direct path also exists along with the multipath components, and the attenuation due to fading can be characterized with Rician statistics. In this paper, we present simplified bit error rate (BER) expression of binary phase shift keying (BPSK) modulation using RS code in slow flat Rician fading. The analytical BER values have been validated through MATLAB based simulations. A detailed discussion on the development of the simulation code is also included.
