Enhancing Wireless Security Over Weibull Fading Multicast Channel

Abstract

This paper aims to the study of security in wireless transmission system through Weibull fading single-input multiple-output multicast channels considering multiple receivers and eavesdroppers. At first, the analytical expressions for the probability of non-zero secrecy multicast capacity and the ergodic secrecy multicast capacity are derived in closed-form to illustrate the numerical results. Then the closed-form expression for the secure outage probability is obtained to examine the secure outage behaviour. Finally, a comparison between Weibull and Rayleigh fading channel is presented to demonstrate the impact of Weibull fading parameter on the secrecy performance of the proposed scenario.
