Rayleigh rician
WebThe derivation of the probability density function of amplitude is more involved than for Rayleigh fading, and a Bessel function occurs in the mathematical expression. It has been proposed to approximate this expression by the model for Nakagami fading, however, the behaviour of Nakagami and Rician fading in deep fades is essentially different. http://www.wirelesscommunication.nl/reference/chaptr03/ricenaka/ricenaka.htm

WebAug 29, 2024 · 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 may be more applicable. Rayleigh fading is a special case of two-wave with diffuse power (TWDP) fading. WebFor Rician fading, the slope of the outage probability versus C/I is the same as for Rayleigh fading. For Nakagami fading, the slope is steeper, similar to that of m-branch diversity reception of a Rayleigh fading signal. Method for Link Evaluation. The nakagami approximation appeared less suitable to approximate a Rician channel.
