Abstract :
In this paper we study single and multi-carrier ultra-wideband (UWB) communications focusing on spectral efficiency and system performance. We begin by examining the spectrum of the general form of single carrier ultra-wideband systems and argue that multi-carrier UWB systems provide better utilization of the available spectrum. We then describe a general form for multi-carrier UWB systems and study their performance focusing on the multipath interference (MI) and interchannel interference (ICI). The results of this analysis lead us to a signal design approach for a multi-earner UWB system named UWB-OFDM.
