Digital Modulation in Rayleigh Fading in the Presence of Cochannel Interference and Noise
TLDR
The error rate performance of several digital modulation methods in a fading environment and in the presence of one cochannel interference and AWG noise is analyzed and a unique formula emerges for different PSK systems.Abstract:
The error rate performance of several digital modulation methods in a fading environment and in the presence of one cochannel interference and AWG noise is analyzed. A unique formula emerges for different PSK systems. It is shown how this information can be used in determining acceptable degradation caused by cochannel interference in the case of a digital mobile communication system.read more

TL;DR: The problem of optimal carrier recovery and detection of digitally phase modulated signals on fading channels by using a nonstructured approach is presented, i.e. no constraint is placed on the receiver structure, and shows that the optimal carrier Recovery is, under certain conditions, a Kalman filter.
