Modified Gini Index Detector for Cooperative Spectrum Sensing over Line-of-Sight Channels
Sensors, 2023 Recently, the Gini index detector (GID) has been proposed as an alternative for data-fusion cooperative spectrum sensing, being mostly suitable for channels with line-of-sight or dominant multi-path components.

Spectrum Sensing Scheme Measuring Packet Lengths of Interfering Systems for Dynamic Spectrum Sharing
IEEE Access, 2021 For the dynamic spectrum sharing (DSS), this paper proposes a spectrum sensing scheme that measures packet lengths of interfering systems. DSS requires spectrum sensing techniques to measure a length of time for which the interfering systems use a ...

Dynamic primary-secondary spectrum sharing with cellular systems [PDF]
Proceedings of the 5th International ICST Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2010 This paper considers primary-secondary spectrum sharing when the primary is a cellular system. Sharing is allowed if primary communications can withstand additional interference, rather than if there are no primary communications. We consider cases when primary and secondary systems cooperate (cooperative sharing) and when they do not (coexistent ...

Noncooperative equilibrium solutions for spectrum access in distributed cognitive radio networks [PDF]
, 2008 This paper considers the problem of channel selection and dynamic spectrum access in distributed cognitive radio networks. The ability of a cognitive radio to adaptively switch between channels offers tremendous scope to optimize performance.

Enabling Sharing in Auctions for Short-Term Spectrum Licenses [PDF]
, 2015 Wireless spectrum is a valuable and scarce resource that currently suffers from under-use because of the dominant paradigm of exclusive-use licensing. We propose the SATYA auction (Sanskrit for truth), which allows short-term leases to be auctioned and ...
