Cooperative communication that integrates cognitive radio and non-orthogonal multiple
access is recognized as an emerging technology for fifth-generation and beyond wireless …

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 …

We investigate the secrecy beamforming in two-way relay channels (TWRC) with physical
layer network coding (PNC). The multi-antenna relay broadcasts the superimposed signal of …

We study the secrecy transmission of uplink non-orthogonal multiple access (NOMA) with
single antenna and multi-antenna users in presence of an eavesdropper. Two phases are …

A key feature of the non-orthogonal multiple access (NOMA) technique is that users with
better channel conditions have prior information about the messages of other users. The …

The secrecy outage probability (SOP) performance is investigated for a cooperative non-
orthogonal multiple access system under eavesdropping attack, where a base station …

With the increasing demand for security in many sectors, such as defense and health
systems, developing secure Internet of Things (IoT) networks is a matter of great urgency …

Aiming at high energy consumption and information security problem in the simultaneous
wireless information and power transfer (SWIPT) multi-user wiretap network, we propose a …

In this paper, a novel approach is introduced to study the achievable delay-guaranteed
secrecy rate, by introducing the concept of the effective secrecy rate (ESR). This study …

This paper investigates the covert communication of cooperative non-orthogonal multiple
access (NOMA) systems, where the near user serves as a decode-and-forward (DF) relay …
