WebJun 10, 2024 · Small Scale Fading affects almost all forms of wireless communication and overcoming them is a necessity to increase efficiency and decrease error. Fast Fading: It occurs mainly due to reflections for surfaces and movement of transmitter or receiver. WebFading signals occur due to reflections from ground surrounding buildings (clutter) as well as scattered signals from trees, people, towers, etc. often an LOS path is not available so the first multipath signal arrival is probably the desired signal (the one which traveled the shortest distance) allows service even when Rx is severely
