Low complexity online convolutional beamforming [article]

Sebastian Braun, Ivan Tashev
2021 arXiv   pre-print
In this work, we propose a low complexity convolutional beamformer using a Kalman filter derived affine projection algorithm to solve the adaptive filtering problem.  ...  Convolutional beamformers integrate the multichannel linear prediction model into beamformers, which provide good performance and optimality for joint dereverberation and noise reduction tasks.  ...  CONCLUSION We proposed a scalable system integrating joint adaptive MPDR beamforming and reverberation cancellation using a Kalman filterderived affine projection algorithm.  ...
