To enhance the spectrum utilization efficiency, cognitive radio and full duplex techniques are
considered as the two main effective methods. For the two-way communication underlay full …

Cognitive radio and full duplex transmissions are regarded as two effective techniques to
improve the spectral efficiency. By combining the two promising techniques, the problem of …

This paper considers a full-duplex underlay cognitive radio (CR) network with a full-duplex
cognitive base station (CBS) transmitting signals to a set of half-duplex downlink secondary …

With the recent advances in radio modules capable of carrying out full duplex (FD)
communication, the spectrum efficiency promised by the concept of Cognitive radio (CR) can …

This paper presents the results of an investigation into bi-directional communication in
spectrum sharing-based cognitive radio (Bi-CR) systems. A Bi-CR system can increase the …

A power allocation scheme for the secondary user when the primary user employs the full
duplex relay (FDR) is proposed in cognitive radio system. When the FDR is deployed in …

In this paper, we investigate resource allocation algorithm design for full-duplex (FD)
cognitive radio systems. The secondary network employs a FD base station for serving …

In this paper, we examine a full-duplex transmission scheme for cognitive cooperative radio
networks (CCRNs) to improve capacity. In this network, the secondary transmitter and …

In traditional cognitive radio networks (CRNs), the interweave, underlay, overlay, and hybrid
spectrum sharing schemes are only spectrum-efficient in specific circumstances. In order to …

In order to effectively solve the problem of spectrum shortage, cognitive radio and full duplex
have been proposed and widely studied in recent year. In this paper, we integrate cognitive …
