摘要

针对慢瑞利衰落信道，提出了一种自适应前向误差控制和调制方案。该自适应方案采用一组不同速率的RS码，并根据信道的状态采用多种相移键控(MPSK)调制方案。它使用信道估计器来选择最合适的共调(编码调制)方案。仿真结果表明，该自适应方案显著提高了误码率和吞吐量性能。

Adaptive coding and modulation using Reed Solomon codes for Rayleigh fading channels

An adaptive forward error control and modulation scheme is proposed for slow Rayleigh fading channels. The adaptive scheme employs a family of RS codes of different rates and multiple phase shift keying (MPSK) modulation schemes according to the states of the channel. This uses a channel estimator to select the most appropriate codulation (coded-modulation) scheme. Simulation results show that the adaptive scheme gives significant improvement in the BER and throughput performance.
