Non-orthogonal multiple access (NOMA) is one of the promising radio access techniques for
performance enhancement in next-generation cellular communications. Compared to …

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) …

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 …

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 …

Today's wireless networks allocate radio resources to users based on the orthogonal
multiple access (OMA) principle. However, as the number of users increases, OMA based …

Non-orthogonal multiple access (NOMA) has been widely recognized as a promising way to
scale up the number of users, enhance the spectral efficiency, and improve the user-fairness …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

This paper presents a full-duplex device-to-device (D2D)-aided cooperative nonorthogonal
multiple access (NOMA) scheme to improve the outage performance of the NOMA-weak …

We propose a full-duplex (FD) cooperative non-orthogonal multiple access (NOMA) system
with dual users, where a dedicated FD relay assists the information transmission to the user …

We study a downlink non-orthogonal multiple access system with cooperative full-duplex
relaying, where the near user in terms of the base station (BS) is enabled to act as a full …
