Abstract
This paper introduces two methods for the integration of a dynamically steered beamforming filter with acoustic echo cancellation (AEC) and adaptive generalized sidelobe canceler (GSC) based beamforming methods. We evaluate the performance of a beamforming system with moving and changing source positions. Individual contributions of adaptive beamforming and steering independent AEC processing methods are evaluated for high level echo cancellation in a typical office environment. The results show that the proposed adaptive beamforming method increases the overall AEC performance even if GSC adaptation would be disturbed by dynamic beam steering.
