A comprehensive analytical perspective of ASEP for Beaulieu-Xie fading channels

This study presents the average symbol error probability (ASEP) performance of a single-input single-output communication with imperfect phase error (IPE) and without IPE over the Beaulieu-Xie fading channels. The Beaulieu-Xie fading model is proposed recently and it is a popular characterization for the line-of-sight and non-line-of-sight environments. The proposed theoretical analysis, which is based on the probability density function, is enough general and applicable in some real-life scenarios. For both cases, closed-form exact, approximate, and asymptotic expressions are derived for the ASEP of different modulation types. Finally, exact simulations have been introduced to confirm the accuracy of the theoretical findings obtained and present insights into the considered scheme performance.
