In this paper, we investigate different secrecy energy efficiency (SEE) optimization problems
in a multiple-input single-output underlay cognitive radio (CR) network in the presence of an …

The integration between orthogonal frequency division multiple access (OFDMA), non-
orthogonal multiple access (NOMA), and cognitive radio (CR) technology has been recently …

The power domain non-orthogonal multiple access (PD-NOMA) performs reasonably well
under perfect successive interference cancellation (SIC) conditions. However, under …

In this paper, we investigate the resource allocation of mobile edge computing (MEC) in
cognitive capacity harvesting networks (CCHNs) when non-orthogonal multiple-access …

Non-orthogonal multiple access (NOMA) along with cognitive radio (CR) have been recently
configured as potential solutions to fulfill the extraordinary demands of the fifth generation …

This paper considers uplink solar-powered cognitive radio networks (CRNs) where multiple
secondary users (SUs) transmit data to a secondary base station (SBS) by sharing a …

The integration of simultaneous wireless information and power transfer (SWIPT) in multi-
carrier non-orthogonal multiple access (NOMA) systems has been recently investigated as a …

In this paper, we investigate the energy minimization for the cellular networks with non-
orthogonal multiple access (NOMA). Different from most of existing studies in NOMA …

Abstract Wireless Powered Communication Network (WPCN) consists of Hybrid Access
Point (HAP) that performs power transmission and data collection at the same time, and …

In this paper, we propose a joint beamforming and power-splitter optimization technique for
simultaneous wireless power and information transfer in the downlink transmission of a …
