Small-scale fading is a temporary effect that describes rapid fluctuations in the amplitude and phase of a radio signal over a short period of time or distance.  Multipath is a propagation phenomenon that occurs when radio signals reach a receiving antenna by two or more paths. Multipath propagation results in a time-varying signal as the mobile moves position.  Multipath and fading can significantly impact the performance of wireless communication systems.
