Ultra-Wideband (UWB) technolog is based on the transmission of radio signals over frequency bandwidths from 500 MHz to several GHz. Its unique charateristics can be exploited for the design of high data rate wireless ccommunication systems, as well as location-based and imaging applications. the development and optimization of swuch systems require a precise knwoldge o the radio transmission medium. This book examines all aspects of the propagation channel for UWB systems, starting with a presentation of UWB technology, with a particular emphasis being placed on applications, spectrum regulation issues and different communication techniques. Next, the author's introduce the theoretical foundations of electromagnetic wave or signal propagation and give an overview of channel sounding techniques adapted for UWB signals. Finally, the two main principles of UWB channel modeling are described and illustrated: first, deterministic channel modeling, based on simulation of the propagation phenomena in a given environment; and second, statistical channel modeling, which relies on experimental analysis of the main channel characteristics.
