UMTS mobile positioning simulator for vehicle location
Sha Tao, S. Rodriguez, Ana Rusu · 2010
In this paper, a tool for simulating UMTS mobile positioning in vehicular environment has been developed. The primary function of this simulator is to locate the UMTS mobile in realistic propagation environments. This tool first models the network configuration and radio propagation in a vehicular scenario. Based on the system level model, it then simulates the pilot signal transmitted by a base station to a mobile station through the 3GPP WCDMA FDD downlink. The received pilots at mobile station are processed to obtain the time-difference-of-arrival estimates which are used to construct the hyperbolic equations for mobile position calculation. The simulator has been implemented in the Matlab and Simulink environment.
