Non-Orthogonal multiple access (NOMA) holds promise as a spectrally efficient multiple
access scheme for 5G communication networks. This work investigates the performance of …

Sixth generation (6G) networks must guarantee radio-resource availability for coexisting
users and machines. Here, non-orthogonal multiple access (NOMA) can address resource …

Non-orthogonal multiple access (NOMA) scheme is considered as a promising technology
for 5G networks due to its ability to increase the spectral efficiency. In this paper, by …

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 …

Although the use of coordinated direct and relay transmission (CDRT) in non-orthogonal
multiple access (NOMA) can extend the coverage, its duplicated transmission reduces the …

In contrast with orthogonal multiple access (OMA) technologies, non-orthogonal multiple
access (NOMA) technology can achieve higher spectral efficiency and support more users …

A coordinated direct and relay transmission is proposed using uplink non-orthogonal
multiple access (UP-NOMA). A two-user UP-NOMA scenario is considered, where a cell …

This paper studies the application of cooperative techniques for non-orthogonal multiple
access (NOMA). More particularly, the fixed gain amplify-and-forward (AF) relaying with …

In this study, non‐orthogonal multiple access (NOMA)‐based coordinated direct and relay
transmission (CDRT) is considered, where a base station (BS) directly communicates with …

NOMA (Non-orthogonal multiple access) system becoming a strong candidate for 5G
cellular system of its high spectral efficiency. This paper considers an optimal power …
