由于多径效应和移动台运动等影响因素，使得移动信道对传输信号在时间、频率和角度上造成了色散，即时间色散、频率色散、角度色散等等，因此多径信道的特性对通信质量有着重要的影响，而多径信道的包络统计特性则是我们研究的焦点。根据不同无线环境，接收信号包络一般服从几种典型分布，如瑞利分布、莱斯分布等。在此专门针对服从瑞利分布的多径信道进行模拟仿真，进一步加深对多径信道特性的了解。-Due to multipath effects and the mobile station sports and other factors, making the mobile channel for the transmission signal in time, frequency and angle, causing a dispersion, namely the time dispersion, frequency dispersion, angular dispersion, etc., so the multipath characteristics of the channel quality of communication have an important impact, and multipath channel envelope statistical properties are the focus of our study. Depending on the wireless environment, the received signal envelope generally subject to several typical distributions such as Rayleigh, Rice distribution. In this specific multipath Rayleigh distribution channel simulation, further deepen the multipath channel characteristics understanding.
