What is the difference between Rayleigh and Rician fading?

WebWhen there is a dominant LOS path, the Rician fading model becomes more suitable, but we will be focusing on Rayleigh. Note that Rayleigh and Rician models do not include the primarily path loss between the transmitter and receiver (such as the path loss calculated as part of a link budget), or any shadowing caused by large objects. WebMay 28, 2016 · • Rayleigh fading is the specialised model for stochastic fading when there is no line of sight signal, and is sometimes considered as a special case of the more generalised concept of Rician fading.
