An Enhanced Affine Projection Algorithm Based on the Adjustment of Input-Vector Number [PDF]
Entropy, 2022 An enhanced affine projection algorithm (APA) is proposed to improve the filter performance in aspects of convergence rate and steady-state estimation error, since the adjustment of the input-vector number can be an effective way to increase the ...

HIGH-RESOLUTION SATELLITE IMAGE TRIFOCAL TENSOR SOLUTION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 This study presents an efficient algorithm for solving the affine trifocal tensor problem in high-resolution satellite imagery. Because the imaging mode of high-resolution satellites is usually a line-center projection and the field of view is ...

The Generalized Complex Kernel Affine Projection Algorithms [PDF]
Circuits, Systems, and Signal Processing, 2021 AbstractThe complex kernel adaptive filter (CKAF) has been widely applied to the complex-valued nonlinear problem in signal processing and machine learning. However, most of the CKAF applications involve the complex kernel least mean square (CKLMS) algorithms, which work in a pure complex or complexified reproducing kernel Hilbert space (RKHS). In this

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.
