Error probability in Nakagami-Rice channel

The well-known Rayleigh channel's error probability is compared with those for differential phase shift keying and noncoherent frequency shift keying signals that are transmitted through a 'Nakagami-Rice' severe fading channel. Two parameters, alpha and omicron, describe the fading channel and can be estimated by measuring the intensities of the known preamble (synchronizing) signal. Fading is found to be less severe than in the Rayleigh channel.
