Non-orthogonal multiple access (NOMA) is one of the most effective techniques for meeting
the spectrum efficiency (SE) requirements of 5G and beyond networks. This paper presents …

Non‐orthogonal multiple access (NOMA) has recently attracted a lot of attention as a
promising multiple access technology to be used in the fifth generation (5G) cellular …

NOMA is a promising radio access technique for next-generation wireless networks. In this
article, we investigate the NOMA-based cooperative relay network. We begin with an …

Cooperative non-orthogonal multiple access (NOMA) system employs user relaying to
enhance performance. Although full-duplex (FD) user relaying scheme does not incur …

This letter proposes time sharing (TS)-based half/full-duplex (HD/FD) cooperative non-
orthogonal multiple access (CRNOMA) schemes, namely, TS-HD-CRNOMA and TS-FD …

In this study, a cooperative non‐orthogonal multiple access (NOMA) scheme is investigated
in an underlay cognitive radio network. With this aim, a number of secondary users are …

Nonorthogonal multiple access (NOMA) promises higher throughput than the conventional
orthogonal access by multiplexing the signal of a weak user with that of a strong one …

We consider downlink non-orthogonal multiple access transmission where an access point
communicates with a set of near and far users via a full-duplex multiple antenna relay. To …

This paper proposes a cooperative uplink–downlink non orthogonal multiple access
(NOMA) in an overlay cognitive radio network (CR). We examine the impact of imperfect …

Envisioned as a promising component of the future wireless Internet-of-Things (IoT)
networks, the non-orthogonal multiple access (NOMA) technique can support massive …
