Non-orthogonal multiple access (NOMA) aims to increase the spectral efficiency of fifth
generation networks by relaxing the orthogonal use of radio-resources. In this paper, a …

In this paper, we investigate a non-orthogonal multiple access (NOMA) assisted multi-
antenna two-way relay system, where multi-antenna users apply NOMA to support …

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 …

Non-Orthogonal Multiple Access (NOMA) has the potential to increase the spectral efficiency
of fifth generation (5G) networks by allowing simultaneous transmission to/from multiple …

In conventional cooperative non-orthogonal multiple access (NOMA) networks, spectral
efficiency loss occurs due to a half-duplex constraint. To address this issue, we propose an …

This paper studies a two-user cooperative non-orthogonal multiple access network with a
novel cooperation scheme, where the source communicates with the near user directly or …

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 …

In this paper, we consider non-orthogonal multiple access (NOMA) relaying networks, where
one base station communicates with two mobile users with the aid of multiple relays. We …

It is challenging for the base station (BS) to serve multiple cell-edge users concurrently with
data rate guarantee due to limited power and spectrum resource. Using the relay enhances …

The nonorthogonal multiple access (NOMA) well improves the spectrum efficiency which is
particularly essential in the Internet of Things (IoT) system involving massive number of …
