摘要

M-QAM是一种频谱利用率较高的调制方式

但是在多径环境下其性能的恶化限制了它在无线通信中的应用.本文结合Rician衰落特性

提出了采用最大比合并和选择式合并以有效改善M-QAM系统性能的方法.这种方法在实际中有着广泛的应用前景.

Abstract

M-QAM(Quadrature Amplitude Modulation) has a high frequency efficiency

but its quality will degrade largely under the multi-path environments

thus limits its application in wireless communications.This paper proposes a way to improve the performance of M-QAM in Rician fading

using maximum ratio and selective combining.It is expected that the method will gain wider use in reality.
