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

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

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 propose a spectrum-sharing protocol for a cooperative cognitive radio
network based on non-orthogonal multiple access technology, where the base station (BS) …

In this paper, we analyze the performance of an energy harvesting (EH)-assisted overlay
cognitive non-orthogonal multiple access (NOMA) system. The underlying system consists of …

In this paper, cooperative cognitive multiple access schemes with harvesting capability are
considered for improving the energy efficiency and spectrum utilization. We consider three …

In this paper, we examine non-orthogonal multiple access (NOMA) and relay selection
strategy to benefit extra advantage from traditional cognitive radio (CR) relaying systems …

To compensate for the transmission efficiency in a cooperative non-orthogonal multiple
access (NOMA) system, we enable in-band full-duplex (IBFD) and two-way cognitive …

Improving spectral efficiency under a certain energy limitation is an important design metric
for future wireless communications as a response to the growing transmission demand of …

Recently, non-orthogonal multiple access (NOMA) and radio frequency (RF) energy
harvesting (EH) techniques are applied in cooperative communication systems for 5G and …
