Abstract :
The phase ambiguity problem in detecting phase modulated signals transmitted over a time-variant frequency-nonselective Rayleigh fading channel is addressed. A unified way for signal detection in an unknown channel based on the noncoherent estimator-correlator receiver is presented. We explain how this receiver can be used in conjunction with linear modulations. We provide a method for estimating the required number of pilot symbols and the need for tracking.
