<p>The present invention provides a method for reciprocity error calibration, comprising steps of: measuring downlink channel response H DL ; measuring uplink channel response H UL ; calculating one of a user equipment reciprocity error E m and a base station reciprocity error E b utilizing least square LS criterion based on the H DL and H UL in accordance with a reciprocity model calculating the other one of the E m and E b based on the calculated one of E m and E b utilizing an algorithm adopting minimum mean square error MMSE criterion; and performing a reciprocity error calibration operation utilizing the calculated user equipment reciprocity error E m and base station reciprocity error E b . There is further provided a reciprocity error calibration device for performing the reciprocity error calibration method. The reciprocity error calibration method and the reciprocity error calibration device according to the present invention may provide better reciprocity error calibration performance.</p> |
