摘要
本文主要介绍无线信道的基本概念和特性,并且通过自定义的MATLAB环境下的M文件对无线信道的典型例子-平稳衰落信道进行仿真。在仿真过程中,我们主要是对幅度服从莱斯分布和瑞利分布的衰落信道进行仿真。最后,我们对数字调制后的信号如移相键控(PSK)信号通过莱斯衰落信道时的性能进行仿真,并得到相应的分析结果。
This paper introduces the basic concepts and the characteristics of mobile radio channels, and models the flat fading channels in MATLAB by means of user - defined m - files. In the simulation, we main introduce and model Rician fading channel and Ray -leigh fading channel . Finally, a MATLAB based simulation example is presented, which comprises performance estimation of phase shift keying (PSK) signaling over a Rician fading channel.
