Physical Layer Security Over $\alpha$-$\kappa$-$\mu$ and $\alpha$-$\eta$-$\mu$ Fading Channels

In this correspondence, the physical layer security of wireless systems under generalized α-κ-μ and α-η-μ fading with arbitrary fading parameters is analyzed in terms of the secrecy outage probability (SOP). To this end, novel analytical expressions for the lower bound of the SOP are derived. Moreover, an asymptotic secrecy analysis is investigated for each corresponding SOP to get the secrecy diversity gain. Monte Carlo simulations are provided to assess the accuracy of the proposed analytical framework.
