摘要： A method is provided for use in calibrating a plurality of antennas comprised in an antenna array and wherein the antenna array comprises at least one gain control circuitry. The method comprises: transmitting one or more pre-defined signals by at least one antenna comprised in the antenna array; receiving at one or more of the antennas comprised in the antenna array, a signal derived from a corresponding pre-defined signal transmitted by the at least one antenna; and for each of the one or more antennas, detecting whether there is any difference between the corresponding one or more pre-defined signals transmitted thereto and the respective one or more signals received thereat, and if in the affirmative, applying the detected differences in a process of calibrating the one or more antennas comprised in the antenna array, and wherein the process of calibrating the one or more antennas comprised in the antenna array comprises a step of estimating a ratio of complex transmission coefficients for at least two states of the at least one gain control circuitry.
