WebDiversity Techniques for Flat Fading Channels Performance with fading is considerably worse than without fading, especially when the fading is Rayleigh. Performance may be improved by sending the same information on many (independently) fading channels For signaling on L channels, the received signal on the ‘-th channel is: 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?
