In this dissertation, the average bit error rate of binary and quaternary phase-shift keying signals with imperfect carrier phase recovery is investigated assuming a flat slow - , - and - fading channel and the presence of thermal noise. The analysis of average symbol error rate of M-Phase Shift Keying over - , - and - fading channels subject to imperfect carrier phase recovery is investigated. The phase noise is considered to be Tikhonov and Gaussian distributed. More specifically, an analytical expression for the exact average bit error rate is obtained, as well as its corresponding asymptotic expression for large signal-to-noise ratio values. And also, exact and approximate closed-form expressions for ASER i) under non-fading scenario, ii) under - , iii) - and iv) - fading channels, as well as v) its corresponding asymptotic expression for large signal-to-noise ratio values are derived and evaluated. The derived expressions are valid for arbitrary values of the fading parameters, namely , , and , and they are validated by reducing them to particular cases, for which results are available in the literature and by means of Monte Carlo simulations. Several important conclusions concerning the system performance as a function of the channel parameters and loop signal-to-noise ratio are drawn. Keywords: - , - and - fading model, average bit error rate, average symbol error rate, noisy phase, Tikhonov distribution, von Mises distribution.
