快慢衰落与移动台的移动速度,基带信号带宽都有关系 《4》Rayleigh fading是用来描述高斯信号经过多径信道(不用解释了吧)之后,在接受端接收到的信号包络的分布的一种模型。从这个定义可以直观地认为,一个高斯信号经过多径信道之后,其幅度是可以用Rayleigh fading模型来近似的。---“Rayleigh fading是用来描述高斯信号经过...

What is the difference between Rayleigh and Rician fading? Rayleigh fading model assumes that the magnitudeofa signal that has passed through transmission medium will vary randomly, or fade, according to a Rayleigh distribution. ... Rician model considers that the dominant wave can be a phasor su...
signal propagation as well as the effect of heavily built-up urban environments on radio signals.[1][2] Rayleigh fading is most applicable when there is no dominant propagation along a line of sight between the transmitter and receiver. If there is a dominant line of sight, Rician fading ...
1.According to learning communication system,three kinds of channels are studied:additive white gaussian channel,multipath rayleigh fading channel and rician fading channel.通过对通信系统的学习,研究了加性高斯白噪声信道、多径瑞利衰落信道和莱斯衰落信道3种信道。
With an improved Rayleigh fading model and a zero-mean stochastic sinusoid as the scattering and specular components respectively, a stochastic simulation model is proposed for the generation of Rayleigh and Rician fading waveforms. Compared with the existing stochastic models, the proposed simulator need...
