In an RF-powered backscatter cognitive radio network, multiple secondary users
communicate with a secondary gateway by backscattering or harvesting energy and actively …

For an RF-powered cognitive radio network with ambient backscattering capability, while the
primary channel is busy, the RF-powered secondary user (RSU) can either backscatter the …

Ambient backscatter (AB) communications and radio frequency (RF)-powered cognitive
radio networks (CRNs) address the concerns of energy and spectrum scarcities from …

Motivated by the benefits of cognitive radio (CR), energy harvesting (EH), and backscatter
communication (BC) technologies to support Internet of Things (IoT) systems, we investigate …

In this paper, we propose a novel network model for RF-powered cognitive radio networks
and ambient backscatter communications. In the network under consideration, each …

Cognitive radio (CR) is a critical technique to solve the conflict between the explosive growth
of traffic and severe spectrum scarcity. Reasonable radio resource allocation with CR can …

Spectrum scarcity and energy limitation are becoming two critical issues in designing
Internet of Things (IoT). As two promising technologies, cognitive radio (CR) and radio …

In this paper, we investigate deep learning-aided distributed transmit power control in the
context of an underlay cognitive radio network (CRN). In the proposed scheme, the fully …

This paper investigates the time scheduling for a backscatter-aided radio-frequency-
powered cognitive radio network, where multiple secondary transmitters transmit data to the …

In this paper, we study the transmission strategy adaptation problem in an RF-powered
cognitive radio network, in which hybrid secondary users are able to switch between the …
