Abstract
A method for antenna calibration is provided, which includes the following steps: obtaining an updated calibration period T_i after the last time of antenna calibration (S), calculating a calibration sequence of each antenna channel in the calibration period T_i (S); according to the calibration sequence of each antenna channel, calibrating each antenna based on the calibration period T_i, and calculating a calibration error parameter (S); and according to the obtained calibration error parameter, updating the calibration period T_i, and using the updated calibration period T_i for the next time of antenna calibration (S). The technical solutions provided in the present invention, can monitor difference variety of radio channels in real time by the calibration error parameter, and reflect the calibration precision in real time by the reported calibration error parameter. Moreover, the technical solutions provided in the present invention, can adjust the calibration period in real time according to the calibration error parameter, and timely execute rational antenna calibration according to the calibration precision status.
