SYSTEM AND METHOD FOR DETECTING LOCATIONS OF A CUSTOMER PREMISES EQUIPMENT

摘要

The present invention discloses a system for detecting locations of a customer premises equipment in a wireless communication system with one or more base transceiver stations and one is efficient. A plurality of antennas in a base transceiver station receives signals transmitted from a customer premises equipment. A timing detection module extracts the timing offset from the receiving signals and a first calculation module calculates the distance between the BTS and the CPE based on the timing offset. A signal detection module detects magnitudes and phases of the receiving signals and a second calculation module determines a dominant beam according to the antenna pattern and calculates the direction of arrival of the dominant beam. A third calculation module calculates the location of the CPE relative to the base transceiver station based on the distance and the direction of arrival.
