This paper proposes antenna array calibration using frequency selection in OFDMA/TDD systems. In the proposed method, frequencies of good channel conditions are initially selected in order to get accurate channel measurements. Next, relative calibration is performed at the selected frequencies, in which mismatch of analog gains between antennas
is compensated by use of measured channel parameters on uplink and downlink. Thereafter, calibration parameters are interpolated in frequency domain for whole bandwidth. The proposed method keeps accurate channel reciprocity using digital signal processing only. Since the proposed method maintains low-cost and feasible amount of signalling, it is expected to enable exploitation of channel reciprocity at both base station and terminals. |
