In 5G wireless communication networks, Non-Orthogonal Multiple Access (NOMA) has
attracted much attention in recent years. This paper investigates physical layer security of a …

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 …

This study seeks an answer for the impact of the co-channel interference on the leakage rate
of illegitimate relay-assisted power-domain non-orthogonal multiple access (NOMA) …

Physical layer security based on non-orthogonal multiple access (NOMA) and artificial
jamming (AJ) is considered in a one-way amplify-and-forward (AF) relay network with an …

This paper investigates the physical layer security of a full-duplex (FD) Decode-and-Forward
(DF) NOMA network assumed to undergo independent and identically distributed Nakagami …

We investigate physical layer security of an uplink NOMA system consisting of one base
station, multiple users and one eavesdropper. During each uplink transmission, two users …

Enabling cooperation in a NOMA system is a promising approach to improve its
performance. In this paper, we study the cooperation in a secure NOMA system, where the …

In this paper, an underlay cooperative cognitive network using a non-orthogonal multiple
access (UCCN-NOMA) system is investigated, in which the intermediate multiple relays help …

This paper investigates the security at the physical layer of cooperative relay
communications. Inspired by the principle of physical-layer network coding (PNC), we …

The massive connectivity requirement and security issues have become major factors
restricting the further development of the Internet of Things. Nonorthogonal multiple access …
