发明名称 Method and apparatus for locating a mobile station in a spread spectrum communication system
摘要 The method includes receiving (404) by a first base station (212) a signal (215) transmitted from the mobile station (216); demodulating (406) the signal by the first base station (212) to form a demodulated signal; remodulating (408) at least a portion of the demodulated signal to form a reference signal; receiving (412) by the first base station (212) and a second base station (210, 214) a retransmitted signal (217); comparing (414, 16), by the first base station (212), the retransmitted signal (217) with the reference signal to determine a first delay; comparing (414, 416), by the second base station (210, 214), the retransmitted second signal (217) with the reference signal to determine a second delay; and based on the first and second delays, determining (420) a location of the mobile station (216).
