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 … WebRobust Communication in Bursty Impulsive Noise and Rayleigh Block Fading Ahmed Mahmood†, Mandar Chitre†* †Acoustic Research Laborotary, National University of Singapore, Singapore 119227 *Dept. of Electrical and Computer Engineering, National University of Singapore, Singapore 117576 {tmsahme, mandar}@nus.edu.sg ABSTRACT ...
