Abstract
In this paper we discuss the basic concepts underlying cognitive radio (CR) and investigate the ultra wide bandwidth (UWB) technology as one of the enabling transmission techniques for the implementation of CR systems. Firstly, we propose an analytical methodology to assess the interference impact and coexistence issues between narrowband (NB) and UWB communication systems in a realistic scenario. Then, based on this methodology 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
