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

This study presents the average symbol error probability (ASEP) performanceof 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 forthe line-of-sight and non-line-of-sight environments. The proposed theoreticalanalysis, which is based on the probability density function, is enough generaland applicable in some real-life scenarios. For both cases, closed-form exact,approximate, and asymptotic expressions are derived for the ASEP of differentmodulation types. Finally, exact simulations have been introduced to confirmthe accuracy of the theoretical findings obtained and present insights into theconsidered scheme performance.
