摘要
The disclosure relates to an active antenna array (110) for a mobile communication system which comprises a plurality of receive paths (30), a sounding signal generator (105) generating a sounding signal (110), and a coupler (155) for coupling the sounding signal (110) into at least one of a plurality of receive paths (30). A sounding signal extractor (175) substantially removes the sounding signal (10) from digitised ones of the receive signals (120) to form a wanted signal. The disclosure also provides a method for the calibration of the receive path of the active antenna array (110).
