The Cognitive Radio paradigm for Ultra-Wideband systems: The European Project EUWB

In this paper we will discuss the research activity in Cognitive Radio (CR) for Ultra-Wideband (UWB) systems within the FP7 European Project EUWB. We cover the issues related to the interference and coexistence between narrowband (NB) and UWB communication systems in a realistic scenario. We show the great potential of the UWB technology in adapting the transmitted spectrum to counteract NB interference and at the same time to guarantee low spectral emissions over existing narrowband communications. We also discuss the role of location capable radios on cognitive UWB nodes.
