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 the paper, we present a study on the performance analysis of a non-orthogonal multiple
access (NOMA) underlay cognitive hybrid satellite-terrestrial relaying network (CSTRN) and …

Non-orthogonal multiple access (NOMA) is considered to be one of the promising multiple
access (MA) techniques for 5G networks that can provide low latency, high system …

The integration of non-orthogonal multiple access (NOMA) technology and cognitive radio
networks (CRNs) promises to enhance the spectrum utilization efficiency of 5G and beyond …

This paper investigates the impact of partial relay selection scheme (PRSS) on cooperative
underlay cognitive radio (CR) non-orthogonal multiple access (NOMA) networks. Decode …

With the exponential demand for frequency spectrum and the new generation of
communication systems (5G), efficient and less complex ways of using the spectrum are …

In this paper, a downlink scenario of a non-orthogonal multiple access (NOMA) scheme with
power constraint via spectrum sensing is considered. Such network provides improved …

Combining energy harvesting with cognitive radio and nonorthogonal multiple access
(NOMA) techniques will be a notable candidate for improving both energy and spectral …

This paper studies the application of non-orthogonal multiple access (NOMA) to a
cooperative multicast system (termed CM-NOMA). In particular, the multicast subscribers are …

In this letter, we investigate the performance of an overlay cognitive satellite-terrestrial
network comprising a primary satellite source with its multiple terrestrial receivers and a …
