A cooperative localization scheme for 4G wireless communications

Abstract

Along with a vision that foresees the fourth generation (4G) as based on a cellular system that will also support short-range communications among the terminals, in this paper we propose an innovative geolocation scheme that combines long-and short-range location information, respectively retrieved by mean of a hybrid time of arrival/angle of arrival (TOA/AOA) technique in the cellular segment and a TOA technique in the short-range one, in order to enhance the location estimation accuracy with respect to the actual stand-alone hybrid cellular solutions
