The terms slow and fast fading refer to the rate at which the magnitude and phase change imposed by the channel on the signal changes. The coherence time is a measure of the minimum time required for the magnitude change or phase change of the channel to become uncorrelated from its previous value. • Slow fading arises when the coherence time of the channel is large relative to … Webb26 mars 2024 · The aim of this paper is to characterize and study slow fading and fast fading variations of each tap, which is selected from measurement data.
