Sector-Based Detection for Hands-Free Speech Enhancement in Cars
<p/> <p>Adaptation control of beamforming interference cancellation techniques is investigated for in-car speech acquisition. Two efficient adaptation control methods are proposed that avoid target cancellation. The "implicit" method varies the step-size continuously, based on...
