Abstract
A method and system for rapid adaptive coupling equalization in beamforming-based communication systems, particularly sector-based beamforming systems, provides smooth transitions for AEC when the look direction of the communication system changes and when the acoustic environment varies with time. The coefficients of inactive beamformers are modified in real-time, using adaptive beamforming techniques based on the real-time loudspeaker-coupling signal, in order to force the outputs of inactive beamformers to have the same response to the loudspeaker coupling signal as the active beamformer does.
