Title: Wireless Secrecy Under Multivariate Correlated Nakagami-<i>m</i> Fading
Abstract: Current wireless secrecy research in the literature has mainly been performed for one wiretapper under correlated fading.In this paper, a new wireless secrecy framework for multiple wiretappers under multivariate exponentially-correlated (exp.c.) Nakagami-m fading is proposed.Using the distribution of multivariate exp.c.Nakagami-m fading, new, exact, and compact expressions for the ergodic secrecy capacity, and secrecy outage probability (SOP) under multiple wiretappers are obtained for an integer fading parameter m.A secrecy analysis is also performed for the first time in this paper using an adaptive on/off transmission encoder under multivariate exp.c.Nakagami-m fading.A secrecy analysis with three wiretappers under quadrivariate exp.c.Nakagami-m fading is also given, which shows the effectiveness of the new framework.Simulation results are shown to exactly match theoretical predictions.
