In this paper, we consider a non-orthogonal multiple access (NOMA) based mixed free
space optical–radio frequency (FSO-RF) system with imperfect channel state information …

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 …

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 …

Simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) is
becoming a prospective technology in realizing extremely low power transmission and …

Non-orthogonal multiple access (NOMA) has been proposed as a promising multiple access
approach for 5G mobile systems because of its superior spectrum efficiency. However, the …

In this letter, we investigate the secrecy outage performance of a cooperative non-
orthogonal multiple access (NOMA) network, where a base station (BS) communicates with …

Full-duplex (FD) relay systems including a transmit antenna selection and a non-orthogonal
multiple access (NOMA) methods are analyzed under presence of multiple eavesdroppers …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

A new paradigm of uplink non-orthogonal multiple access along with multiple
eavesdroppers to achieve secrecy transmission is studied in this paper. We investigate the …

As an important partner of fifth generation (5G) communication, the internet of things (IoT) is
widely used in many fields with its characteristics of massive terminals, intelligent …
