Abstract

Summary: 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. Abstract : This paper proposes new analytical average symbol error probability expressions for a single‐input single‐output communication over Beaulieu‐Xie fading channels. First, the ASEP of the considered system with imperfect phase error is derived. Then, the ASEP expressions for non‐coherent M ‐ary frequency shift keying, M ‐ary differential phase‐shift keying and differential quadrature phase shift‐keying modulation are proposed based on the derived probability density function. The derived expressions are confirmed by numerical simulations and the effects of different parameters on the system performance are investigated.
