Variable step-size affine projection sign algorithm
Electronics Letters, 2012 Proposed is a variable step-size affine projection sign algorithm (APSA) based on the minimisation of mean-square deviation. Because the proposed algorithm calculates the optimum step size in every iteration, it ensures an improved performance in terms of convergence rate and misalignment, compared to conventional APSAs.

A Variable Step‐Size Leaky LMS Algorithm [PDF]
Wireless Communications and Mobile Computing, 2021 The leaky LMS algorithm has been extensively studied because of its control of parameter drift. This unexpected parameter drift is linked to the inadequacy of excitation in the input sequence. And generally leaky LMS algorithms use fixed step size to force the performance of compromise between the fast convergence rate and small steady‐state ...

Variable Step Size Adams Methods for BSDEs
Journal of Mathematics, 2021 For backward stochastic differential equations (BSDEs), we construct variable step size Adams methods by means of Itô–Taylor expansion, and these schemes are nonlinear multistep schemes.

A Variable Step-Size for Sparse Nonlinear Adaptive Filters
2020 28th European Signal Processing Conference (EUSIPCO), 2021 The paper deals with the identification of nonlinear systems with adaptive filters. In particular, adaptive filters for functional link polynomial (FLiP) filters, a broad class of linear-in-the-parameters (LIP) nonlinear filters, are considered. FLiP filters include many popular LIP filters, as the Volterra filters, the Wiener nonlinear filters, and ...

A kurtosis-driven variable step-size LMS algorithm [PDF]
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002 A new technique for adjusting the step-size of the LMS algorithm is introduced. The proposed method adjusts the step-size sequence utilising the kurtosis of the estimation error, reducing therefore performance degradation due to the existence of significant Gaussian-distributed noise.
