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 considers the application of non-orthogonal multiple access (NOMA) into
cooperative cognitive radio (CR) networks with simultaneous wireless information and …

In conventional cognitive radio (CR), the users in secondary network (SN) can only access
the idle spectrum when users in primary network (PN) are absent. This novel strategy …

In this paper, we consider a wireless power transfer assisted uplink non-orthogonal multiple
access (WPT-NOMA) network in Internet of things (IoT), where the battery-less IoT devices …

In this paper, a cooperative non-orthogonal multiple access (NOMA) network is considered,
where a source communicates with two users through an energy harvesting relay. The …

In this paper, we investigate a relay-assisted cooperative spectrum sharing for the
considered non-orthogonal multiple access (NOMA) scheme in cognitive radio networks …

In order to improve the spectrum efficiency and secrecy energy efficiency, in this paper, we
propose a non-orthogonal multiple access (NOMA)-based secure scheme for cognitive radio …

We consider a multiple-input single-output simultaneous wireless information and power
transfer (MISO-SWIPT) system, where a power-splitting protocol is employed at users near …

In this study, we deploy design and performance analysis in new system model using a
relaying model, energy harvesting, and non-orthogonal multi-access (NOMA) network. It is …

The time switching‐based relaying (TSR) scheme is considered in energy harvesting
protocol to implement with its advantage to nonorthogonal multiple access (NOMA) system …
