Physical-Layer Security Analysis over M-Distributed Fading Channels

open access: yesEntropy, 2019
In this paper, the physical layer security over the M-distributed fading channel is investigated. Initially, an exact expression of secrecy outage probability (SOP) is derived, which has an integral term. To get a closed-form expression, a lower bound of
