Abstract

As the number of loudspeakers and microphones in modern devices grows, the task of Acoustic Echo Cancellation (AEC) becomes increasingly computationally expensive as the echo canceller requires the optimization of a large number of adaptive filters. In this paper, an efficient frequency-domain Multiple-Input/Multiple-Output (MIMO) AEC approach is introduced using a Kronecker product-based approximation of the echo paths. In the proposed approach, the trade-off between the approximation accuracy and the computational complexity is controlled by a tuning parameter. This approach is verified for both, time-varying and time-invariant rendering systems and the results show that the proposed approach achieves steady-state performance similar to that of a conventional method at a much lower computational cost.
