Rayleigh flat fading channel
Webboth Rician and Rayleigh fading channels unlike [13] which can only be applied for AWGN channels. • The proposed union bounds for the Rician fading do not contain any binomial … WebChannel information is not available at both Rx and Tx. 3. Rayleigh flat fading channel is considered. The channel information keeps constant for adjacent two symbols. BPSK or QPSK is used. Please illustrate the transmission process and do simulations in Matlab: 3.1 The channel information is not known at Rx, how to do the transmission?
