Abstract
An active antenna array for a mobile communications system is disclosed which comprises a plurality of receive paths in which an individual one of the receive paths is connected between an antenna element and an analogue to digital converter and wherein the analogue to digital converter digitises a receive signal to form a digitised receive signal. The active antenna array further comprises a sounding signal generator for generating a sounding signal in which the sounding signal is supplied to at least two of the plurality of receive paths and a receive signal subtraction device for subtracting a wanted signal from the digitised receive signal.
