Adaptive Spectrum Access: Using the Full Spectrum Space
William D. Horne · 2003
Trends in technology are enhancing the future capability of devices to access the electromagnetic spectrum using the full range of dimensions associated with the spectrum. This increased capability to access the full spectrum “hyperspace” not only improves the ability of systems to use the spectrum but can also reduce interference and the adverse impact to system performance. This paper presents technical research into advanced adaptive techniques and identifies those parameters or characteristics where regulation and policy need to be reviewed. Fundamental to these new adaptive techniques is a behaviorbased approach to design and, possibly, policy. Consequently, this paper also presents a technical case study of one behavior-based approach, Dynamic Frequency Selection, that provides insight into the benefits and possible limitations of such approaches to cognitive radio design and policy.
