Abstract
The combination of wideband transmission and cooperative techniques enables high-precision location-awareness. Wideband transmission provides fine delay resolution and multipath resolvability, while cooperation among nodes can yield significant performance benefit in harsh or infrastructure-limited environments. In this paper, we propose to exploit the geometric relationship inherent in multipath propagation, i.e., multipath geometry, via cooperation among nodes for localization. We characterize the contribution of this multipath geometry in terms of the nodes' squared position error bound, which is the fundamental limit of localization accuracy. Analytical and numerical results validate the benefit of using multipath geometry in wideband cooperative localization.
