Detection-Guided Fast Affine Projection Channel Estimator for Speech Applications
EURASIP 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.

Geometric-algebra affine projection adaptive filter
EURASIP Journal on Advances in Signal Processing, 2021 Geometric algebra (GA) is an efficient tool to deal with hypercomplex processes due to its special data structure. In this article, we introduce the affine projection algorithm (APA) in the GA domain to provide fast convergence against hypercomplex ...
