Managing the radio spectrum
Christos Politis · 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. Communications Regulator) to investigate the issues surrounding the introduction of CR technology.
