Partially coherent detection of PSK signals in Rician channels.

Abstract

Coherent detection which has the best performance in ideal channels suffers in environments where there is significant phase noise (e.g. fading channels). In this thesis, we developed channel models for noisy phase reference and Rician fading channels and assuming that partially coherent detection could be an alternative, we derived metric expressions for partially coherent detection of signals in general and applied it to PSK signals. Simulation programs were run using the developed channel models and the results were compared to other detection schemes under same conditions.
