An Algorithm for Locating Point Scatterers Using a Wide-Band Wireless Network
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2008

A map of the coordinates of the most significant point scatterersin the environment surrounding a wireless network would be useful in many contexts, e.g., in indoor positioning and mapping applications, for channel estimation, and also for wake-up radio schemes. In this work, we investigate the feasibility of creating such a map based on signal propagation path length data gathered at a number of wide-band network transceivers. Differently from previous approaches to this problem, we propose to formulate the point scatterer mapping problem as an assignment problem. Computer simulations show that, under a few simplifying assumptions, it is indeed feasible to position point scatterers using the proposed algorithm.
