Antenna calibration method and device and remote radio frequency unit

The invention provides an antenna calibration method and device and a remote radio frequency unit, and belongs to the technical field of communication. The method comprises the following steps: generating a calibration sequence of a to-be-calibrated channel; determining a calibration response sequence of the to-be-calibrated channel according to the acquired calibration configuration information of the to-be-calibrated channel and the output sequence of the to-be-calibrated channel; and calibrating the to-be-calibrated channel according to the calibration response sequence of the to-be-calibrated channel and the calibration sequence of the to-be-calibrated channel. According to the method, the calibration sequence does not need to be obtained through other systems or functional modules, interaction with other functional entities can be reduced, and the calibration process is simplified; and the calibration response sequence of the to-be-calibrated channel with higher accuracy can be obtained, so that the cali
