WebThe model. Rayleigh fading is a reasonable model when there are many objects in the environment that scatter the radio signal before it arrives at the receiver. The central limit theorem holds that, if there is sufficiently much scatter, the channel impulse response will be well-modelled as a Gaussian process irrespective of the distribution of the individual … WebSep 5, 2014 · For different communication fading channels, the channel impulse response can be modeled using various statistical distributions.
