A cognition scheme, whereby nodes are enabled with the full-duplex technology at the PHY
layer in conjunction with packet fragmentation at the MAC layer, is proposed to increase the …

In traditional cognitive radio networks, secondary users (SUs) typically access the spectrum
of primary users (PUs) by a two-stage" listen-before-talk"(LBT) protocol, ie, SUs sense the …

In traditional cognitive radio networks (CRNs), secondary users (SUs) typically access the
spectrum of primary users (PUs) by a two-stage “listen-before-talk”(LBT) protocol, ie, SUs …

In this paper, we present a new Cognitive Radio (CR) paradigm based on the Full-Duplex
mechanism. In the classical Full-Duplex CR (FD-CR) system, the Secondary User (SU) can …

We consider a cognitive radio network of nodes with full duplex capability where Self-
Interference Suppression (SIS) is not perfect. We have proposed a new scheme for sensing …

In this paper, we propose a novel adaptive scheme for full-duplex communication of
secondary users (SUs) in a cognitive radio network. The secondary network operates …

We consider the Medium Access Control (MAC) protocol design for full-duplex cognitive
radio networks (FDCRNs). Our design exploits the fact that full-duplex (FD) secondary users …

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 …

In this paper, we propose a multi-channel full-duplex Medium Access Control (MAC)
protocol for cognitive radio networks (MFDC-MAC). Our design exploits the fact that full …

In a cognitive radio system the failure of secondary user (SU) transceivers to promptly vacate
the channel can introduce significant access-latency for primary or high-priority users (PU) …
