Patent ID: 8620355

Claim:
A method for wireless positioning measuring locations of terminals, comprising: acquiring synchronization with base stations; collecting a plurality of propagation delay taps for the base stations; setting a valid propagation threshold value; determining a final propagation delay tap among the plurality of propagation delay taps; calculating a time difference of arrival (TDOA) value using the final propagation delay tap; and deriving locations of the terminals using the calculated TDOA value, wherein the plurality of propagation delay taps include a first valid propagation tap, a maximum signal intensity tap, and an intermediate valid propagation tap, the first valid propagation tap is a first received propagation delay tap among the valid propagation delay taps having signal intensity of the set valid propagation threshold value or more, the maximum signal intensity tap is a propagation delay tap having maximum signal intensity among the valid propagation delay taps, and the intermediate valid propagation taps is a propagation delay tap received between receiving timing of the first valid propagation tap and receiving timing of the maximum signal intensity tap, among the valid propagation delay taps.
