Webb11 juli 2014 · When the paths are of different length, then the phase of each path at the receiver differs in phase. If the phase of the two paths are identical, then they add together and no fading occurs. When the phase of the two paths differ by 180 degrees, then they cancel each other and fading occurs. In general, this is called multipath interference. http://www.federica.unina.it/ingegneria/wireless-networks/path-loss-models/
