Acoustic Echo Cancellation for Beamforming Microphone Arrayse loss, the integration of AEC into time-varying beamforming is examined for two broad classes of beamforming structures. Finally, the combination of AEC and beamforming is discussed for multi-channel recording and multi-channel reproduction schemes.

Post-Filtering Techniquester. A theoretical analysis shows that Wiener post-filtering of the output of an optimum distortionless beamformer provides a minimum mean squared error solution. We examine published methods for post-filter estimation and develop a new algorithm. A simulation system is presented to compare the performance of the discussed algorithms.
