In this paper, we investigate the secrecy performance of a full-duplex (FD) non-orthogonal
multiple access (NOMA) relay system under the presence of multiple non-colluding …

To improve the secrecy performance of the untrusted relay system with a multiple-antenna
destination, a novel full-duplex destination jamming scheme with optimal antenna selection …

This paper analyzes the secrecy attributes of a full-duplex relay (FDR) non-orthogonal
multiple access (NOMA) system, where the best relay is chosen from a set of numerous …

The secrecy outage probability (SOP) of cooperative communication systems with optimal
relay selection (ORS) scheme in the presence of an eavesdropper is investigated by …

We have considered a dual‐hop wireless network consisting of a decode‐and‐forward (DF)
relay in presence of an eavesdropper. Relay can correctly decode and retransmit only if the …

In this letter, we consider secure communications in multi-hop relaying systems, where full-
duplex relays (FDRs) operate to enhance wireless physical layer security. Each FDR is …

In this paper, we investigate an artificial-noise (AN) aided secure transmission for non-
orthogonal multiple access (NOMA) full-duplex (FD) relay network. We propose a novel joint …

In this work, we analyze the secrecy outage performance of a dual-hop relay system
composed of multiple-input-multiple-output radio-frequency (RF) links and a free-space …

In this paper, we investigate the secrecy outage performance of a typical cooperative
downlink non-orthogonal multiple access (NOMA) system over Nakagami-m fading channel …

This paper investigates the physical-layer security of the modify-and-forward (MF) protocol in
multi-relay and multieavesdropper networks. Three relay selection critera are developed …
