UWB localization via multipath distortion

Abstract

A new method for non line of sight transmitter localization is suggested, based on the effective bandwidth of different multipath components in the UWB channel response. The method essentially relies on the difference in the distortion applied by the channel to early and to late arrivals in the channel impulse response, the early arrivals have a wider effective bandwidth. Localization results on measured channel responses show the superiority of the new method over a method based on a multipath energy detector.
