The aim of a variable step size normalized least-mean-square (VSS-NLMS) algorithm is to
try to solve the conflicting requirement of fast convergence and low misadjustment of the …

A variable regularized affine projection algorithm (VR-APA) is introduced, without requiring
the classical step size. Its use is supported from different points of view. First, it has the …

A fundamental challenge affecting the performance of a system is the undesired effect of
noise on the system. Practically, real‐time systems are influenced by Gaussian noise and …

A nonparametric adaptive filtering approach is proposed in this paper. The algorithm is
obtained by exploiting a time-varying step size in the traditional NLMS weight update …

We discuss the optimal regularization parameter of the Filtered-Affine Projection (FX-AP)
algorithm suitable for feedforward active noise control. While the original FX-AP algorithm …

In this paper, we propose a variable matrix-type step-size affine projection algorithm (APA)
with orthogonalized input vectors. We generate orthogonalized input vectors using the Gram …

Considering the filters with variable step-sizes outperform their fixed step-sizes versions and
the combination algorithms with proper mixing parameters outperform their components, a …

This paper introduces a variable regularization method for the fast affine projection algorithm
(VR-FAP). It is inspired by a recently introduced technique for variable regularization of the …

This paper presents robust unsupervised decision feedback equalizer (DFE) for acoustic
underwater communications. The proposed equalizer consists of the cascade of four …

A modified generalized normalized gradient descent (GNGD) adaptive algorithm is
proposed. The original GNGD algorithm requires an indirect procedure for the computation …
