Abstract

In this paper, the performance of M-ary phase shift keying (MPSK) modulation with imperfect carrier phase recovery over alpha-kappa-mu and alpha-eta-mu fading channels is investigated, for which noisy phase, assumed to be Tikhonov distributed, is considered. Analytical expressions for the exact average symbol error probability (ASEP) as well as their corresponding asymptotes for high signal-to-noise ratio (SNR) values are obtained. The derived expressions are valid for arbitrary values of the fading parameters, namely alpha, eta, kappa and mu, and they are validated through Monte Carlo simulations. Insightful discussions concerning the system performance as a function of the channel parameters, loop SNR, and over a wide range of SNR are drawn.
