A mobile device includes a received-signal beamformer that adapts to motion of the mobile device

摘要

Signals, preferably acoustic signals, are received at a plurality of signal sensors 302, preferably microphones on a mobile device. Motion of the mobile device is sensed 108 and the received signals are processed using beamforming means 304 within the mobile device, in dependence upon their direction of arrival at the plurality of signal sensors and in dependence upon the sensed motion of the mobile device. The motion sensor 108 may be an accelerometer and/or a gyroscope. The mobile device may be a mobile phone, PDA, portable computer or the like. The signals may be general broadband signals, general narrowband signals, radar signals, sonar signals, antenna signals, radio waves or microwave signals.
