The secrecy outage performance of wireless communication systems operating\nover spatially correlated composite fading channels is analyzed in this paper.\nWe adopt a multiplicative composite channel model for both the legitimate\ncommunication link and the link between the eavesdropper and the legitimate\ntransmitter, consisting of Nakagami-m distributed small-scale fading and\nshadowing (large-scale fading) modeled by the Gamma distribution. We consider\nthe realistic case where small-scale fading between the links is independent,\nbut shadowing is arbitrarily correlated, and present novel analytical\nexpressions for the probability that the secrecy capacity falls below a target\nsecrecy rate. The presented numerically evaluated results, verified by\nequivalent computer simulations, offer useful insights on the impact of\nshadowing correlation and composite fading parameters on the system's secrecy\noutage performance.\n
