Physical Layer Security for Cooperative Relaying Over Generalized- $K$ Fading Channels

In this letter, we analyze the secrecy performance for a cooperative diversity system with amplify-and-forward over generalized-K fading channels. More specifically, some lower bounds on the secrecy performance, such as secure outage probability, average secrecy capacity, and strictly positive secrecy capacity, are derived in closed-form. Finally, we provide simulation results to verify the accuracy of our analytical results.
