Abstract

Ultra wideband (UWB) radios are characterized by the extreme wide bandwidth of their radiated signal. Although in the last years the research and development was focused on systems which use baseband pulse transmission, UWB is defined by its power spectral density and is therefore not restricted to baseband impulse radios. In this paper we propose an alternative system based on multicarrier code division multiple access (MC-CDMA). In addition to the general advantages of multicarrier transmission, MC-CDMA UWB promises also benefits especially in UWB radios, like transmitter range, frequency notching and narrowband suppression, which are described in this paper.
