The development of unmanned aerial vehicles (UAVs) is one of the driving forces for
revolutionizing wireless communications in the modern era. Although there are many unique …

Non-orthogonal multiple access (NOMA) continues to receive enormous attention as a
potential technique for improving the spectral efficiency (SE) of wireless networks. Although …

The cognitive industrial Internet of Things (CIIoT) can improve transmission performance by
utilizing the spectrum licensed to a primary user (PU), providing that the normal …

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 work, a cognitive relay network (CRN) with interference constraint from the primary
user (PU) with a mobile end user is studied. The proposed system model employs a half …

This paper investigates the performance analysis of cognitive-inspired wireless-powered
non-orthogonal multiple access (NOMA) systems, where two collaborative schemes are …

This paper analyzes the performance of a spectrally-efficient non-orthogonal multiple access
(NOMA) based signalling scheme in which two selected users are scheduled for uplink …

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 …

In this paper, a dual-hop underlay cognitive relay network (CRN) with a best-relay selection
(BRS) scheme under spectrum-sharing constraints from the primary user (PU) is …

In this paper, we study the application of the non orthogonal multiple access (NOMA) and
orthogonal multiple access (OMA) scheme to cooperative cognitive radio network. We …
