The Impact of Side Information on Physical Layer Security Under Correlated Fading Channels

Abstract

In this paper, we investigate the impact of side information (SI) on the performance of physical layer security (PLS) under correlated fading channels. By considering non- causally known SI at the transmitter and exploiting the copula technique to describe the fading correlation, we derive closed- from expressions for the average secrecy capacity (ASC) and secrecy outage probability (SOP) under positive/negative depen- dence conditions. We indicate that considering such knowledge at the transmitter is beneficial for system performance and ensures reliable communication with higher rates, as it improves the SOP and brings higher values of the ASC.
