WIRELESS POSITION ESTIMATION APPARATUS AND METHOD

摘要

A wireless position estimation apparatus may include a wireless communications unit receiving radio signals including positional information related to a plurality of APs from the plurality of APs including a plurality of antennas, a radio signal processing unit combining radio signals received from the plurality of antennas or selecting one of the radio signals, depending on whether or not channel gains of the respective antennas are changed, for a respective AP, a distance calculating unit measuring received signal strength indication (RSSI) values of the radio signals combined or selected by the radio signal processing unit and calculating distance values to the APs using the measured RSSI values, and a position estimating unit estimating a position of a terminal using the calculated distance values and the positional information.

1. A wireless position estimation apparatus comprising:
a wireless communications unit configured to receive radio signals including positional information related to a plurality of access points (APs) from the plurality of APs including a plurality of antennas; a radio signal processing unit configured to combine radio signals received from the plurality of antennas with each other or select one of the radio signals, depending on whether or not channel gains of the respective antennas are changed, for a respective AP; a distance calculating unit configured to measure received signal strength indication (RSSI) values of the radio signals combined with each other or selected by the radio signal processing unit for a respective AP, and calculate distance values to the APs using the measured RSSI values; and a position estimating unit configured to estimate a position of a terminal using the distance values calculated for respective APs and the positional information.
