In this article, we propose a novel cooperative non-orthogonal multiple access (NOMA)
scheme to guarantee the secure transmission of a specific user via two time slots. During the …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same resource block to improve the spectral efficiency. Whereas due to the resource …

In this paper, we consider a cooperative relay network consisting of a source, a destination
and multiple decode‐and‐forward relays in the presence of multiple eavesdroppers, which …

This paper investigates the adverse effects of co-channel interference (CCI) on the secrecy
achievable rate (SAR) performance of illegitimate decode-and-forward full-duplex two-way …

This paper investigates transmit antenna selection (TAS) to improve the secrecy
performances in MIMO secure cooperative relay systems with an adaptive decode-and …

In this paper, we develop a secure non-orthogonal multiple access (NOMA)-based two-way
relay network, in which two users wish to exchange their NOMA signals via a trusted relay in …

In this paper, we consider a secrecy relaying communication scenario where all nodes are
equipped with multiple antennas. An eavesdropper has the access to the global channel …

Differentsystemmodels utilizing nonorthogonal multiple access (NOMA) have been
successfully studied to meet the growing capacity demands of the Internet of Things IoT) …

In this paper, we consider the physical layer security of a downlink non-orthogonal multiple
access (NOMA) system, in which users' quality of service (QoS) requirements are …

Due to the successive interference cancellation (SIC) technique, Non orthogonal multiple
Access (NOMA) users have the capability of decoding the other paired users sharing the …
