Detection-Guided Fast Affine Projection Channel Estimator for Speech Applications

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2007
In various adaptive estimation applications, such as acoustic echo cancellation within teleconferencing systems, the input signal is a highly correlated speech. This, in general, leads to extremely slow convergence of the NLMS adaptive FIR estimator.
