“…2) Amount of fading and channel quality estimation index: The derived expression for the arbitrary-order raw moments is of primary importance for the evaluations of the channel quality estimation index (CQEI) [33]. Being initially proposed in [34] as an alternative long-term performance criterion helping to evaluate and optimize wireless systems functioning in the case of fading, it found wide acceptance in a variety of applications [35], [36]. The classical definition of CQEI is given either in terms of the raw moments of the instantaneous SNR or in terms of the amount of fading (AoF), which in its turn is evaluated as the variance of γ normalized by γ2 , i.e,…”

The research presents the closed-form outage analysis of the newly presented α-modification of the shadowed Beaulieu-Xie fading model for wireless communications. For the considered channel, the closed-form analytical expressions for the outage probability (including its upper and lower bounds), raw moments, amount of fading, and channel quality estimation indicator are derived. The carried out thorough numerical simulation and analysis demonstrates strong agreement with the presented closed-form solutions and illustrates the relationship between the outage probability and channel parameters.
