Abstract :
This paper introduces a new adaptive filter structure for a class of event-based signals corrupted by quasi-periodic noise. The event driven adaptive filter emerges from Widrow´s adaptive filter, exploiting specific properties of event-based signals such as unpredictable time appearance and limited time duration. Experimental tests verify improved filter performance of the proposed solution.
