Abstract:
A method for locating an RFID transponder is proposed. The method comprises generating a plurality of measurement signals based on a magnetic field measured by a plurality of sensors. The method further comprises determining a respective degree of correlation for each of the plurality of measurement signals with a reference signal. The reference signal is based on a data sequence assigned to the RFID transponder. In addition, the method comprises determining a position of the RFID transponder based on the degrees of correlation of the plurality of measurement signals.
