This paper investigates the performances of secure
communications over non-small-scale fading channels. Specifically,
considering three different cases when the main and
eavesdropper channels experience independent lognormal fading,
correlated lognormal fading, or independent composite fading, we
study the average secrecy capacity and secrecy outage [including
the probability of nonzero secrecy capacity (PNSC) and secure
outage probability (SOP)] for these channel conditions. The approximated
closed-form expressions for the average secrecy capacity,
PNSC, and SOP are derived for these three different types
of non-small fading channels. The accuracy of our performance
analysis is verified by simulation.
