Cognitive Radio has been recognized as a promising way to improve spectrum efficiency of
wireless communications by exploiting under-utilized licensed spectrum in temporal …

In this paper, we demonstrate that despite the power constraints on all transmit nodes
caused by the interference temperature limit (ITL) imposed by the primary user, power …

In this paper, we investigate the physical-layer security of a multi-user multi-eavesdropper
cognitive radio system, which is composed of multiple cognitive users (CUs) transmitting to a …

In this paper, a wireless energy harvesting and information transfer protocol in cognitive
relay networks is investigated, where an energy harvesting secondary network shares the …

Cooperative relay technology has recently been introduced into cognitive radio (CR)
networks to enhance the network capacity, scalability, and reliability of end-to-end …

Due to overshadow and channel fading, many mobile users are unable to receive the signal
transmitted from satellite directly. Hence, some relay stations should be set to help this type …

In this paper, the secrecy outage performance of an underlay cognitive decode-and-forward
relay network over independent but not necessarily identical distributed Nakagami-m fading …

This work investigates the multiple-input multiple-output system in the context of the
selective decode-and-forward multihop relay network under short-packet communications to …

In this paper, the outage behavior of dual-hop multiuser multirelay cognitive radio networks
under spectrum-sharing constraints is investigated. In the proposed cognitive radio network …

This paper proposes and analyzes cognitive multihop decode-and-forward networks in the
presence of interference due to channel estimation errors. To reduce interference on the …
