1. A method of processing signals at a device, the method comprising:

  • receiving signals, over a range of angles, at a plurality of sensors of the device, the received signals including an interfering signal received from an interfering source location;

    determining an interference delay pattern between receipt of signals at the sensors corresponding to receipt of a signal from the interfering source location;

    generating a plurality of regularization signals having a delay pattern matching the determined interference delay pattern;

    using the generated regularization signals to determine beamformer coefficients to be applied by a beamformer; and

    the beamformer applying the determined beamformer coefficients to the signals received by the plurality of sensors, thereby generating a beamformer output.
