Cognitive radio (CR) and full-duplex (FD) have received extensive attention and research
due to their high spectrum efficiency, which can effectively solve the problem of low …

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 …

In this paper, we evaluate the fundamental trade-off between the energy efficiency (EE) and
the spectral efficiency (SE) of an uplink full-duplex (FD) cognitive radio (CR) channel in …

Sharing the spectrum with in-band full-duplex (FD) primary users (PUs) is a challenging and
interesting problem in the underlay cognitive radio systems. The self-interference introduced …

In the dynamic spectrum access (DSA) paradigm for cognitive radio networks (CRNs), one of
the commonly used Medium Access Control (MAC) schemes is designed on basis of the …

Sharing the spectrum with in-band full-duplex (FD) primary users (PU) is a challenging and
interesting problem in the underlay cognitive radio (CR) systems. The self-interference …

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 …

Wireless networks with their ubiquitous applications have become an indispensable part of
our daily lives. Wireless networks demand more and more spectral resources to support the …

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 this paper, we consider a cognitive radio system with some of secondary users (SUs)
equipped with multiple antenna full-duplex transceivers. We design a hybrid system to …
