This paper proposes a novel non-orthogonal multiple access (NOMA)-based cooperative
transmission scheme for a spectrum-sharing cognitive radio network (CRN), whereby a …

In this letter, a cooperative underlay cognitive non-orthogonal multiple access (NOMA)-
based coordinated direct and relay transmission is investigated. Specifically, exact closed …

In this paper, the performance of non-orthogonal multiple access (NOMA) based cooperative
spectrum sharing in hybrid satellite-terrestrial networks (HSTNs) is investigated, where the …

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 …

This letter studies the application of non-orthogonal multiple access to a downlink cognitive
radio (termed CR-NOMA) system. A new cooperative transmission scheme is proposed …

In this letter, a decode-and-forward cooperative underlay cognitive radio (CR) non-
orthogonal multiple access (NOMA) network is studied. Exact closed-form expressions for …

This paper proposes a cooperative nonorthogonal multiple access (CNOMA) scheme in a
full-duplex (FD) relaying cognitive radio network (CRN), where a primary user (PU) …

This correspondence paper investigates a novel non-orthogonal multiple access (NOMA)
assisted overlay spectrum sharing framework for multiuser cognitive radio networks toward …

Non-orthogonal multiple access (NOMA) is emerging as a promising, yet challenging,
multiple access technology to improve spectrum utilization for the fifth generation (5G) …

This paper considers the application of non-orthogonal multiple access (NOMA) into
