摘要：
Frequency domain adaptive filters are attractive in applications requiring a large number of coefficients such as acoustic echo cancellation (AEC). Our recent paper derived a not-so-restrictive fixed common step-size bound for the generalized multidelay adaptive filter (GMDF). Based on this bound, this paper introduces a new frequency-domain regularization for the GMDF algorithm. Extensive simulation results demonstrate the usefulness of our algorithm in the scenario of speech input signals.
