WebRayleigh fading model considers the fading is caused by multipath reception. Rayleigh fading model assumes that the magnitude of a signal that has passed through transmission medium will vary randomly, or fade, according to a Rayleigh distribution. Rayleigh fading is a reasonable model when there are many objects in the Webcoders over the multipath ﬂat Rayleigh fading communication channel; a channel that models the effect of small-scale fading in a multipath propagation environment with no dominant line of sight between the transmitter and the receiver [10]. We also investigate the proposed Fading-GRAND with SIMO (single chiropractic organizations
