WebAug 10, 2011 · hi. you can use a 2-tap delay line to model a two path rayleigh fading channel , i.e. , if x is the signal passed through the channel , the output of the channel will be : y=a1.*x+a2.*x (n-taw) where a1 and a2 are rayleigh random variables (slow rayleigh fading envelopes in each path) and taw is the relative delay between two paths . regards. Web数据在信道中的传输速率受到信道带宽、信噪比、调制方式等因素的限制。信噪比不能任意提高，因为信噪比越高，传输速率就越快，但是信噪比达到一定程度后，再提高信噪比对传输速率的提升就非常有限了。
