Physical layer secrecy performance with transmitter antenna selection over dissimilar fading channels

In this paper, we investigate the physical layer secrecy performance of a multi-input single-output system. The system consists of multiple antennas at transmitter and single antenna at receiver in the presence of a passive eavesdropper with single antenna over dissimilar fading channels. On the assumption that legal channel is subject to Rayleigh fading while illegal channel undergoes Hoyt fading, expressions for the existence probabilities of secrecy capacity and secrecy outage are derived by using statistical characteristics of signal-to-noise ratio. Analytical results are verified by Monte-Carlo simulations.
