In the fifth generation (5G) of wireless communication systems, hitherto unprecedented
requirements are expected to be satisfied. As one of the promising techniques of addressing …

Non-orthogonal multiple access (NOMA) is an essential enabling technology for the fifth-
generation (5G) wireless networks to meet the heterogeneous demands on low latency, high …

This paper investigates a downlink multiple-input single-output intelligent reflecting surface
(IRS) aided non-orthogonal multiple access (NOMA) system, where a base station (BS) …

Driven by the rapid escalation of the wireless capacity requirements imposed by advanced
multimedia applications (eg, ultrahigh-definition video, virtual reality, etc.), as well as the …

Over the last few years, interference has been a major hurdle for successfully implementing
various end-user applications in the fifth-generation (5G) of wireless networks. During this …

The Internet of Things (IoT) is rapidly becoming an integral part of our life and also multiple
industries. We expect to see the number of IoT connected devices explosively grows and will …

Fifth generation (5G) wireless networks face various challenges in order to support large-
scale heterogeneous traffic and users, therefore new modulation and multiple access (MA) …

Abstract Power Domain Non-Orthogonal Multiple Access (PD-NOMA) is a potential
technology for the next generation of cellular networks. Compared to classical orthogonal …

Non-orthogonal multiple access (NOMA) has received tremendous attention for the design
of radio access techniques for fifth generation (5G) wireless networks and beyond. The basic …

This letter studies the impact of relay selection (RS) on the performance of cooperative non-
orthogonal multiple access (NOMA). In particular, a two-stage RS strategy is proposed, and …
