— Ultra wideband technology shows promise for precision ranging due to its fine time resolution to resolve multipath fading and the presence of lower frequencies in the baseband to penetrate walls. While a concerted effort has been conducted in the extensive modeling of the indoor UWB channel in recent years, to our knowledge only two papers have reported(More)

— Fine time resolution enables Ultra-Wideband (UWB) ranging systems to reliably extract the first multipath arrival corresponding to the range between a transmitter and receiver, even when attenuated in strength compared to later arrivals. Bearing systems alone lack any notion of time and in general select the arrival coinciding with the strongest path,(More)
— While the frequency-dependence of the wireless channel may be negligible for narrow to wideband signals, it has been shown that modeling this dependence for bandwidths in excess of 2 GHz improves channel reconstruction up to 40%. Yet to our knowledge, only Molisch et al. have done so for the ultra-wideband channel. Their benchmark frequency model however(More)
Despite the potential for high-speed communications, stringent regulatory mandates on Ultra-Wideband (UWB) emission have hindered its commercial success. By combining resolvable UWB multipath from different directions, Multiple-Input Multiple-Output (MIMO) technology can drastically improve link robustness or range. In fact, a plethora of algorithms and(More)
