We present an improved state-space frequency-domain acoustic echo canceler (AEC), which makes use of Kalman filtering theory to achieve very good convergence performance, particularly in double talk. Our contribution can be considered threefold: The proposed approach is designed to suit an automotive wideband overlap-save (OLS) setup, to operate best in(More)
Reproducible evaluation of dynamic and nonlinear systems is a nontrivial problem. However, automotive speech processing algorithms such as hands-free systems have to be tested under numerous time-variant conditions in a repeatable fashion. The current way of generating time-varying echo paths, as described in ITU-T Recommendation P.1110, relies on a(More)
