Physical Layer Security Performance Analysis of the FD-Based NOMA-VC System

IEEE Access, 2019
In this paper, we consider the secrecy outage probability (SOP) of a cooperative non-orthogonal multiple access (NOMA) vehicular communication (VC) system, where the relay is working in either half-duplex (HD) or full-duplex (FD) mode. We assume that all

Secrecy performance of cooperative cognitive radio networks under joint secrecy outage and primary user interference constraints

, 2020
In this paper, we investigate the secrecy performance of a Cooperative Cognitive Radio Network (CCRN) in the presence of an eavesdropper (EAV). The secondary users (SUs) are subject to three constraints which include peak transmit power level and ...

Physical Layer Security for Keyhole-based NOMA Downlink Systems with a Multi-antenna Eavesdropper

Journal of Telecommunications and Information Technology
This paper investigates the physical layer security of downlink nonorthogonal multiple access (NOMA) systems operating over a degenerate keyhole channel in the presence of a multi-antenna eavesdropper. We propose a joint antenna selection framework with

Secrecy outage probability of cognitive small-cell network with unreliable backhaul connections

, 2019
In this paper, we investigate the secrecy performance of underlay cognitive small-cell radio network with unreliable backhaul connections. The secondary cognitive small-cell transmitters are connected to macro base station by wireless backhaul links. The

Physical Layer Security in an Untrusted Energy Harvesting Relay Network

IEEE Access, 2019
The security performance in an amplify-and-forward dual-hop untrusted relay network is considered. It is assumed that the source and multiple destinations are equipped with multiple antennas, and the information transmission is aided by a single-antenna ...

Secrecy Outage Analysis for Cooperative NOMA Systems with Relay Selection Schemes

, 2019
This paper considers the secrecy outage performance of a multiple-relay assisted non-orthogonal multiple access (NOMA) network over Nakagami-m fading channels. Two time slots are utilized to transmit signals from the base station to destination.

On the physical layer security of correlated Weibull fading channels with transmitter side information in the presence of a passive eavesdropper

Alexandria Engineering Journal
In this paper, we analyze the performance of physical layer security (PLS) in Weibull fading wiretap channels (WTC), leveraging realistic channel propagation models in which the channel coefficients of the main (transmitter-to-legitimate receiver) and ...
