This paper is concerned with the transmission of confidential data over Rayleigh fading channels with three terminals, a sender, a receiver, and an eavesdropper. The transmitter has single antenna and both receivers have multiple antennas (SIMOME). Considering the problem of secure communications between two nodes over a Rayleigh fading channel in the presence of an eavesdropper, by using majorization theory, we investigate the impact of correlation among receive antennas on the outage probability. Finally, numerical results confirm again the accuracy of the theoretical analysis.This paper is concerned with the transmission of confidential data over Rayleigh fading channels with three terminals, a sender, a receiver, and an eavesdropper.

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

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 dependence 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.In this paper, we investigate the impact of side information (SI) on the performance of physical layer security (PLS) under correlated fading channels.

In this paper, the secrecy performance of single-input-multiple-output systems over correlated κ-μ shadowed fading channels is investigated. In particular, based on the classic Wyner's wiretap model, we derive analytical expressions for secure outage probability (SOP) and the probability of strictly positive secrecy capacity (SPSC) over correlated κ-μ shadowed fading channels. In order to further study the impact of channel parameters on the secrecy performance, novel SOP and the probability of SPSC over independent and identically distributed κ-μ shadowed fading channels are also obtained. In addition, we discuss the asymptotic expressions of the SOP and the SPSC. The match between the analytical results and simulations is excellent for all parameters under considerations. It is interesting to find that the results show that when the signal-to-noise ratio of the main channel is lower than that of the eavesdropping channel, the larger value of correlation coefficient is helpful to improve the secrecy performance and vice versa.In this paper, the secrecy performance of single-input-multiple-output systems over correlated κ-μ shadowed fading channels is investigated.
