Abstract
In order to differentially detect a multiple-phase shift keying (MPSK) signal, a predetermined number of phase signals are stored at successive symbol time points. Next, a plurality of phase differences between the phase signals stored in the above are calculated. Subsequently, a symbol value of the MPSK signal is determined or estimated at a current symbol time point using the calculated phase differences and using symbol values already determined at a plurality of preceding symbol time points.
