TERMINAL LOCATION ESTIMATION SYSTEM AND METHOD, AND POSITION ESTIMATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve the location estimation precision of a terminal in estimating a terminal location from an incoming-direction estimation straight calculated based on a wireless communication signal between the terminal and a wireless base station. SOLUTION: A terminal location estimation system includes: received-power calculation parts A1 to AN for measuring received power of signals received by a plurality of antennas; incoming-direction estimation parts B1 to BN for estimating the incoming direction of an electric wave from the received signal; and a weighing terminal location estimation part C for calculating the incoming-direction estimation straight from the estimated incoming direction and a coordinate of a communicating base station for the electric wave and for estimating a terminal location by executing weighing for further increasing weighing as the received power is higher, based on the incoming-direction estimation straight of the respective base stations and the respective received power.
