Abstract
The disclosure relates to an active antenna array for a mobile communication system which comprises a plurality of receive paths, a control unit for generating a sounding signal, and a coupler for coupling the sounding signal into at least one of a plurality of receive paths. A switch is used to switch the output of one the plurality of receive paths between one of a receiver and a calibration unit. The disclosure also provides a method for the calibration of the active antenna array which comprises generating an initial sounding signal, coupling the initial sounding signal into at least one of a plurality of receive paths to generate an adjusted sounding signal, comparing the adjusted sounding signal with an initial sounding signal and then generating calibration parameters.
