ABSTRACT
This paper investigates the secure communication over Non-Line-of-Sight (NLOS) Ultraviolet (UV) links suffering from turbulence-induced fading, where the transmitter and the receiver or eavesdropper cone axes lie in the same plane or different planes and can be pointed in arbitrary directions. The closed-form expressions of the Average Secrecy Capacity (ASC), the Secrecy Outage Probability (SOP) and the Probability of Positive Secrecy Capacity (PPSC) are derived to evaluate the secrecy performance. Finally, simulation results are provided to verify the accuracy of our derivations and show the effect of transmission power and elevation angle on the ASC, SOP and PPSC.
