An indoor multipath-assisted single-anchor UWB localization method

Abstract

In this paper, an indoor Ultra Wide Band (U localization system relying on a single-anchor setup is prese Conventional UWB localization systems require at least i anchors for trilateration, which leads to high system complexity and cost. Hence new technologies, such as the Virtual An (VA) approach are emerging to achieve single-anchor localiza The VA concept models Multipath Components (MPCs individual distance measurements thus exploiting reflections the environment to aid the accuracy of the localization. Exi single-anchor approaches require a priori information of pre” tag positions to estimate the current tag position. The novelty of this paper is an initialization method that enables estimate tag position without the use of a priori position information. The proposed solution is validated using both simulations and measurements. Both simulations and measurements have shown positive results, which indicates that single-anchor location is feasible.
