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

In this article, an energy efficiency (EE) maximization problem of cooperative nonorthogonal
multiple access (CNOMA) network is proposed to jointly determine the user pairing …

This letter investigates an energy harvesting (EH)-assisted coordinated direct and relay
transmission in an overlay cognitive non-orthogonal multiple access (NOMA) system …

In this article, we exploit nonorthogonal multiple access (NOMA) for simultaneous energy
and information transfer in a wireless-powered Internet-of-Things (IoT) network. As double …

To improve the radio spectral efficiency for 5G and beyond, novel radio access techniques
need to be designed to accommodate unprecedented number of connected devices, and …

This paper applies machine learning to optimize the transmission policies of cognitive radio
inspired non-orthogonal multiple access (CR-NOMA) networks, where time-division multiple …

The continued growth of the industrial Internet of Things (IoT) paves the way for the fifth
industrial revolution (Industry 5.0), which is expected to further enhance the wireless …

In this study, the performance of a secondary network in cognitive radio (CR) is studied in
the context of vehicle-to-everything (V2X). The non-orthogonal multiple access (NOMA) is …

To further improve spectral efficiency, this paper considers a non-orthogonal multiple access
(NOMA)-assisted overlay cognitive radio network consisting of a pair of primary users and a …

Recently, non-orthogonal multiple access (NOMA)-enabled cognitive satellite-unmanned
aerial vehicle (UAV)-terrestrial networks have attracted extensive attention for the …
