Abstract :
Independent, frequency nonselective, fast, Rayleigh diversity fading channels with nonidentical branch statistics are assumed. The optimum combining receiver structure for differential phase shift keying (DPSK) with differential detection is derived based on the maximum a posteriori probability criterion. Both explicit, closed-form bit error probability (BEP) expressions for 2-, 4- and 8-DPSK and simple Chernoff upper bounds to these BEP´s are obtained for arbitrary order of diversity
