WebSep 25, 2024 · The BER as a function of SNR (Eb/No) for the two systems in Figs. 2 and 3 is plotted as shown in Fig. 4. It is found that the output of the BER with Rayleigh fading is the lowest relative to that of the AWGN channel alone. Therefore, the fading model of the Rayleigh performs better where there is a clear line of sight signal.

Web2.1. Rayleigh Fading Channel Rayleigh fading occurs due to the multilink reception. In Rayleigh fading model the effect of the environment spreading to a larger area on a radio signal. It is one of the cheapest models of the signal propagation (i.e. for ionosphere and troposphere). Rayleigh fading is most applicable when WebFor a Rayleigh fading wireless channel the BER value is higher than AWGN reference channel. Due to this the performance over the Rayleigh fading wireless channel is significantly poor, even at high SNR. The main objective of the transmitter diversity techniques is to reduce the value of the BER as SNR increases in the Rayleigh
