Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also called a communication channel) will vary randomly, or fade, … See more 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 … See more As described above, a Rayleigh fading channel itself can be modelled by generating the real and imaginary parts of a complex number … See more • Rayleigh fading channel signal generator using the Dent model (Matlab) See more Since it is based on a well-studied distribution with special properties, the Rayleigh distribution lends itself to analysis, and the key features that affect the performance of … See more • Fading • Rayleigh scattering • Rician fading • Non-line-of-sight propagation See more the navara kost

"WebDiversity Techniques for Flat Fading Channels Performance with fading is considerably worse than without fading, especially when the fading is Rayleigh. Performance may be improved by sending the same information on many (independently) fading channels For signaling on L channels, the received signal on the ‘-th channel is: " - Rayleigh flat fading channel
