Abstract
This paper proposes two algorithms for an error reduction technique/demodulator to minimize the effects of the propagation channel on DMPSK modulated symbols transmitted over a flat fading channel. The first algorithm uses a Hibert transform whereas the second algorithm uses a parametric two-ray time domain model to estimate the absolute value of the phase differential of the carrier from the envelope of the carrier. This is demonstrated on a mobile radio channel.
