The channel model is characterized by a log-normal shadowing component and a Rayleigh fast fading component on the useful link and on interfering links.
Abstract— An analytical approach to derive the level crossing rate (LCR) and the average fade duration (AFD) for the signal-to- interference ratio (SIR) in ...
Rayleigh fading is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices.

Sep 20, 2016 · This question concerns fading channels in wireless communication, but its essence is still statistics and distributions, so I pose it here.

Assume that we can average over Rayleigh fading. Take the lognormal shadowing to have a standard deviation of σ = 8 dB, and the path loss component to be 4.
Small-scale fading. Rayleigh fading – fading margin. How many dB fading margin, against Rayleigh fading, do we need to obtain an outage probability of 1%?.
In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables.
In this work, we derive the asymptotic expressions of the average symbol error probability (SEP) of a wireless system over the Weibull-lognormal fading channel.
For medium-scale fading (commonly referred to as shadowing), the underlying signal power can be well described by lognormal statistics, i.e., the signal mea-.
In this paper, we first provide a very accurate estimation of the capacity of a single-input single-output system operating in a log-normal environment.
