In this paper, we present a hybrid ambient backscatter communication (ABC) assisted
framework for radio frequency (RF) powered cognitive radio networks (CRNs). In these …

Unmanned aerial vehicles, sometimes known as drones, are becoming increasingly
common in communications networks, drawing interest from both business and academia …

Non‐orthogonal multiple access (NOMA) has been adopted as a potential research
candidate in the fifth generation wireless networks owing to its better user fairness and high …

The UAV-assisted energy harvesting cognitive wireless network has the feature of fast
layout, remarkable spectrum efficiency (SE) and energy efficiency (EE), thereby being …

We consider a cognitive radio system, in which a secondary transmitter harvests energy from
a primary transmitter's RF signal. The secondary transmitter, which provides decode-and …

Non‐orthogonal multiple access (NOMA), which is an effective solution to improve spectral
efficiency, has been considered as an emerging candidate for the fifth generation multiple …

In this paper, non-orthogonal multiple access (NOMA) in cooperative relay system is
considered, where a source node communicates with a pair of energy harvesting (EH) user …

Massive connectivity and limited energy are main challenges for the beyond 5G (B5G)-
enabled massive Internet of Things (IoT) to maintain diversified Qualify of Service (QoS) of …

The cooperative non-orthogonal multiple access (NOMA) networks with one pair primary
user and one pair cognitive user share the same spectrum resource via a common relay is …

The deployment of unmanned aerial vehicle (UAV)-enabled cognitive radio system in the
area covered by primary network is studied in this letter. The UAV shares the spectrum with …
