Abstract:
1. A mobile device comprising: a plurality of signal sensors for receiving signals; a beamformer configured to process the received signals in dependence upon their direction of arrival at the plurality of signal sensors; a motion sensor configured to sense motion of the mobile device and to provide an indication of the sensed motion of the mobile device to the beamformer, wherein the beamformer is configured to process the received signals in dependence upon the indication of the sensed motion of the mobile device, wherein the signals comprise: (i) at least one primary signal having a respective at least one principal direction of arrival at the plurality of signal sensors, and (ii) interfering signals having respective interfering directions of arrival at the plurality of signal sensors, wherein the beamformer is configured to apply beamformer coefficients to the received signals to thereby apply greater levels of suppression to signals received with the interfering directions of arrival than to signals received with the at least one principal direction of arrival.
