Method for optimizing error filtering based on coherence

摘要

Common adaptive active sound and vibration control algorihtms usch as LMS or RLMS optimize adaptive filters to minimize the mean squared error.Error isngal filtering has been used to mdify the adaptive update and emphasize cna cellation n areas in the frequency domain where cancellation is practicla or desirable.A method is described here to dexing and error filter that yields an error signal proportional to the conerene between the referenc3e and error micorphones.
