IEEE Vehicular Technology Magazine, 2009
In this article, we focus on the vision of spectrally aware CR that comprises handsets automatically making use of under-utilized spectrum by sequentially hopping into spectrum gaps across a broad frequency range. The topics discussed in this article are based on a project funded by Ofcom (the U.K.

Spectrum and radio resource management
IEEE Vehicular Technology Magazine, 2008Wireless technologies are rapidly evolving to allow operators to deliver more advanced multimedia services. High-speed packet access (HSPA) for uplink and downlink is seen as an intermediate evolutionary step since the first wave of wideband code division multiple access (WCDMA)-based networks rollout, while evolved universal mobile telecommunications ...

Radio spectrum monitoring for cognitive radio
2011 2nd International Conference on Wireless Communication, Vehicular Technology, Information Theory and Aerospace & Electronic Systems Technology (Wireless VITAE), 2011It is commonly believed that there is a crisis of spectrum availability due to tremendous growth in the wireless based services and evolution of new radio communication technologies. In fact, there are many areas of the radio spectrum which are not fully utilized.

Deep Learning-Based Spectrum Sensing in Cognitive Radio: A CNN-LSTM Approach
IEEE Communications Letters, 2020For most existing spectrum sensing detectors, the design of their test statistics relies on certain signal-noise model assumptions and hence, their detection performance heavily depends on the accuracy of the assumed models.

Cooperative Spectrum Sensing Optimization in Energy-Harvesting Cognitive Radio Networks
IEEE Transactions on Wireless Communications, 2020This article focuses on the issue of cooperative spectrum sensing (CSS) in a mobile energy-harvesting cognitive radio network (EH-CRN), where secondary transmitters (STs) are powered by the radio-frequency (RF) signal emitted from primary transmissions ...

Needs for the Radio Spectrum and for Radio Spectrum Research
1978This report is an initial attempt to identify and emphasize needs for radio spectrum and for related spectrum research to serve as the basis for planning for Efficient Use of the Spectrum Program at OT/ITS. However, any need or requirement for spectrum does not relate only to OT/ITS goals, but should be of concern to many individuals and organizations.

Radio Spectrum Management in Australia
IEEE Wireless Communications, 2016The radio spectrum is managed for the Federal Government (Commonwealth) by the Australian Communications and Media Authority (ACMA), an independent statutory authority within the Commonwealth Government's communications portfolio that reports directly to the Minister for Communications and the Arts. The title of this Minister (as well as the incumbent)
