When tinit = 0, the fading process starts at time zero. A positive value of tinit advances the fading process relative to time zero while maintaining its continuity.
WebbGaussian and Rayleigh Distribution. Difference between AWGN and Rayleigh Fading. 1. Introduction. Rayleigh fading coefficients and AWGN, or additive white gaussian noise [↗], are two distinct factors that affect a wireless communication channel. In mathematics, we can express it in that way.
Webbfor fast fading channels and outage capacity for slow fading channels. However, analyses show that the outage capacity is a misconception. In this paper we use the 1st order Gaussian-Markov process with coherence coefficient as the unified model for slow and fast fading channels, the capacity of which without channel side information is studied.

Slow fading occurs when the coherence time of the channel is larger relative to the delay constraint of the channel. The amplitude and phase change imposed by the channel can be considered roughly constant over the period of use. Slow fading can be caused by events such as shadowing, where a large gamecube goblin commander
