Rayleigh multipath channel
Webis transmitted through a multipath Rayleigh fading WSSUS channel h(r; t). Therefore, h(r; t) follows a zero-mean com- plex Gaussian random process in the t variable. At the receiver, the received signal, s(t), is given by 03 s(t) = n(t) + eJwt L u(t - r)h(r; t) d7 (6) 'In this paper, complex signal representations are used. The physical signal WebJan 31, 2024 · It is observed that the BER is minimum for AWGN and maximum for RAYLEIGH. From the figures we can see that the AWGN channel has lower BER than different fading channels. The Rayleigh fading channel has higher BER than Rician and AWGN fading channels. The Rician fading channel has BER between the AWGN and …
