This paper introduces the concept of equivalent
channel for mutual information performance analysis of multiple symbol differential MPSK (M-phase shift keying) over time correlated,time-varying flat-fading communication channels. It is proven that differential detection scheme theoretically preserves the channel information capacity when the observation interval
approaches infinity. A state space approach is used to model
time correlation of time varying channel phase. It is shown
that the differential decoding implicitly uses a sequence of
innovations of the channel process time correlation and this
sequence is essentially uncorrelated (i.i.d). It enables utilization of multiple-symbol differential detection, as a form of block by-block maximum likelihood sequence detection for capacity achieving mutual information performance
