BASE STATION APPARATUS AND CALIBRATION METHOD |
摘要 |
When using a plurality of antenna elements, calibration is performed appropriately, while preventing processing time from increasing. A base station apparatus has a plurality of antenna elements; a combiner configured to receive and combine downlink transmission signals, each including a reference signal, from monitor ports provided corresponding to the antenna elements; a channel estimator configured to estimate a channel of the reference signal for each of the antenna elements; and a calibration controller configured to calculate a calibration correction value to be applied to each of the antenna elements based upon channel estimation result. |

1. A base station apparatus comprising:
a plurality of antenna elements; a combiner configured to receive and combine downlink signals, each including a reference signal, from monitor ports provided corresponding to the plurality of antenna elements; a channel estimator configured to perform channel estimation for estimating a channel of the reference signal for each of the plurality of antenna elements; and a calibration controller configured to calculate a calibration correction value to be applied to each of the antenna elements based upon channel estimation result. |
