Detection-Guided Fast Affine Projection Channel Estimator for Speech Applications

Jennifer, Yan Wu; Homer, John; Rombouts, Geert; Moonen, Marc

Description

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. As a result, for such applications, the affine projection algorithm (APA) or the low-complexity version, the fast affine projection (FAP) algorithm, is commonly employed instead of the NLMS algorithm. In such applications, the signal propagation...[Show more]
