Secrecy Performance of MISO Fluctuating Two-Ray Fading Channels

In the fluctuating two-ray (FTR) fading channel, we analyze the physical layer security performance of the multiple-input single-output (MISO) millimeter wave communication system in the presence of an eavesdropper. To get physical and technical insights into the impact of channel parameters on secrecy performance, we first derive the numerical expressions of the security of the physical layer security, such as the average secrecy capacity and the secrecy outage probability. Then we derive the lower bound of secrecy outage probability and the probability of strictly positive secrecy capacity. The theoretical results are corroborated by Monte Carlo simulations.
