Rayleigh and rician distributions

WebWe provide new analytical results for the κ-μ extreme (κ-μ-E) fading distribution, which is useful to model propagation conditions more severe than Rayleigh fading. First, we calculate a closed-form expression for the cumulative distribution function in terms of the first-order Marcum Q-function, which allows us to accurately generate κ-μ-E distributed random … WebFeb 29, 2016 · 5. We know that the square of a Rayleigh random variable has exponential distribution, i.e., Let the random variable X have Rayleigh distribution with PDF. f X ( x) = 2 x α e − x 2 / α. Then the random variable Y = X 2 has the PDF given by. f Y ( y) = 1 α e − y / α. For an exponentially distributed r.v. Y with mean E [ Y] = 1.

Webthen the Rician pdf reduces to Rayleigh pdf. When A is large compared with σ, the distribution is approximately Gaussian. Thus, since Ricean distribution covers also Gaussian and Rayleigh distribution, mathematically the Ricean fading channel can be considered to be general case [8].

WebThe Rayleigh distribution is a continuous distribution with the probability density function : f (x; sigma) = x * exp (-x 2 /2 σ 2) / σ 2. For sigma parameter σ > 0, and x > 0.
