Rayleigh channel fading
Webvariation of GRAND designed for multipath flat Rayleigh fad-ing communication channels. Fading can significantly degrade the performance of wireless communication systems, hence diversity approaches are used to combat it. The proposed Fading-GRAND adapts its TEPs to the fading conditions of the underlying channel, outperforming a conventional ... WebFading refers to variation in received signal strength with respect to time due to channel seen by the transmitted signal over the path of travel. Channel fading occurs due to …
