摘要：
In this paper, we analyze the performance of the physical layer security for the classic Wyner's threenode model (including an eavesdropper) over independent/correlated log-normal fading channels. Considering the cases where the main and eavesdropper channels experience independent/correlated log-normal fading, we study the average secrecy capacity and secrecy outage (including the probability of non-zero secrecy capacity and secure outage probability), respectively. The approximated closed-form expressions for the average secrecy capacity, the probability of non-zero secrecy capacity, and secure outage probability have been derived for independent/correlated lognormal fading channels, respectively. Finally, the accuracy of our performance analysis is verified by simulation results.
