Abstract :
A study is presented into the phenomenon of differing BEPs for different symbols transmitted (termed channel non-symmetry) for binary and quaternary differential phase shift keying (2/4-DPSK) in arbitrarily correlated multipath Rician fading channels. The systematic study is facilitated by the moment generating function (MGF) of the decision statistic of 2/4-DPSK. The work unifies many of the previously published results for channel non-symmetry and gives new insight into the problem
