摘要

移动卫星通信中的衰落严重降低了数据传输的性能。本文重点研究了非编码和编码FCMA在衰落环境下的性能。采用RS码非相干解调和硬判决译码对信道进行非频率选择性Rice和Rayleigh衰落建模。利用RS码的Berlekamp-Massey解码来补偿衰落。对特定码和不同的信道参数值计算译码后的误码率。本文的结果是通过仿真技术得到的。它们表明，与未编码的参考系统相比，获得了大量的编码增益。它们也可作为验证模拟研究结果的参考。

Reed-Solomon codes and their performance for FCMA systems in fading satellite channel

Fading in mobile satellite communications severely degrades the performance of data transmission. The emphasis in this paper is on the performance of uncoded and coded FCMA in the fading environment. The channel is modeled with nonfrequency selective Rice and Rayleigh fading using noncoherent demodulation with Reed-Solomon (RS) codes and hard decision decoding. Berlekamp-Massey decoding of RS codes is used to compensate for the fading. The bit error rate (BER) after decoding is calculated for specific codes and for different values of Rician channel parameters. The results of this paper are obtained by simulation techniques. They show that substantial coding gains are obtained compared to the uncoded reference system. They are also useful as a reference for validating the results of simulation studies.
