In this paper, we consider a multi-input multioutput (MIMO) nonorthogonal multiple access
(NOMA) network consisting of one source and two legitimate users (LUs), so-called near …

This paper studies the impacts of antenna selection algorithms in decode‐and‐forward (DF)
cooperative nonorthogonal multiple access (NOMA) networks, where the secure information …

In this paper, we propose a novel transmit antenna selection (TAS) scheme to improve the
physical layer security of two-user non-orthogonal multiple access (NOMA) systems …

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 …

This paper investigates the secrecy performance of a two-user downlink non-orthogonal
multiple access systems. Both single-input and single-output and multiple-input and single …

Owing to the eminent performance gain, non-orthogonal multiple access (NOMA) has been
regarded as a promising approach to achieve high throughput and low latency for the next …

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 …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same frequency band to improve the spectral efficiency. Whereas a security flaw emerges in …

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 …

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 …
