Abstract : Various results have been achieved in unifying the analysis and interpretation of coherent and noncoherent digital data communication systems, by both theoreticians and systems engineers. This research has been concerned with an analysis, unification, and interpretation of the more significant aspects of partially coherent, adaptive, and self-synchronizing digital data receiving system concepts, under a common physical parameter framework. The partially coherent system concepts considered, consist of: (1) The Squaring-Tracking concept, (2) The Pilot-Tone or Residual Carrier concept (employing a first order loop), (3) The Differential Phase Shift Keying (DPSK) concept. Performance characteristics (error probability) for the partially coherent receiver concepts are obtained under a common and unified receiving systems framework. It is assumed that the channel phase modulation effects are tracked in a quasi-steady state mode by the reference acquisition loops, that is with a small value of dynamic phase lag. The partially coherent receivers are assumed to employ realizable filter forms. System performance is illustrated graphically along with interpretive comments and compared with ideal reception (coherent PSK). (Author)
