A Simple Evaluation for the Secrecy Outage Probability over Generalized-K Fading Channels

, 2019
A simple approximation for the secrecy outage probability (SOP) over generalized- K fading channels is developed. This approximation becomes tighter as the average signal-to-noise ratio (SNR) of the wiretap channel decreases.
