Slow fading and fast fading
Webbfast fading, slow fading (shadowing) and path loss. Here we consider several models for small scale fading known as Rayleigh, Ricean, Nakagami and Weibull distributions. WebbThere are two types of fading: fast (multipath) fading and slow (shadow) fading [1]. Fast fading is the rapid fluctuations of the signal over short time-intervals, while slow fading …
