Abstract

Ultra wideband (UWB) signals are being considered for a number of applications including short range/high throughput communications, ranging and high resolution radar. One of, the primary concerns in the design and deployment of UWB systems is the interference generated by UWB systems on other co-located UWB systems and more importantly on narrow band (NB) systems such as GSM and GPS. The interference power levels are a function of (1) the power spectral density(PSD) of the UWB signal over the bandwidth of concern; (2) the spatial density of the UWB transmitters, and the (3) the traffic characteristics of the NW of UWB transmitters. This tutorial paper addresses the spectral properties of the UWB signals.
