The stability of variable step-size LMS algorithms
IEEE Transactions on Signal Processing, 1999Variable step-site LMS (VSLMS) algorithms are a popular approach to adaptive filtering, which can provide improved performance while maintaining the simplicity and robustness of conventional fixed step-size LMS. Here, we examine the stability of VSLMS with uncorrelated stationary Gaussian data.

A NOTE ON THE SELECTION OF THE STEP SIZE IN THE VARIABLE STEP-SIZE STÖRMER METHOD
Computational Methods in Sciences and Engineering 2003, 2003Stormer method is a multistep code with fixed step suitable for the numerical integration of second-order differential equations of the special form y''(x) = f(x,y(x)), y(x0) = y0, y'(x0) = y'0, (1) where the right hand side does not include the derivative of y [4, p.462].

VARIABLE STEP-SIZE STÖRMER METHODS
Computational Methods in Sciences and Engineering 2003, 2003Although it is possible to integrate a special second-order differential equation of the form y''(x) = f(x,y(x)), y(x0) = y0, y'(x0) = y'0 (1) by reducing it to a first order system and applying one of the methods available for those systems, it seems more natural to provide numerical methods to integrate (1) directly without using first derivatives ...

A variable step size LMS algorithm
Proceedings of the 33rd Midwest Symposium on Circuits and Systems, 2002A variable step size LMS algorithm is proposed. The variable step size LMS algorithm has a big step size at the beginning, for a maximum convergence speed, and a much smaller step size after the convergence, for a minimum residual error. The algorithm is derived according to the shortest distance norm between the Kalman gain and the LMS gain vectors ...

The Selection of the Step-Size Factor in the Variable Step-Size CMA
2011This paper analyses the selection of the step-size factor in a new variable step-size constant modulus algorithm (CMA) based on mean square error (MSE) and determines the value range of the step-size factor by computer simulation, which establishes the solid foundation to the convergence superiority of the new algorithm by computer simulation.

A variable step-size affine projection algorithm
Digital Signal Processing, 2010In this paper, we propose a new time-varying step-size for the affine projection (AP) algorithm based on the minimization of the mean-square error (MSE) at each time instant. The step-size is dependent on accessible quantities and, therefore, does not need approximation.

Variable Step Size Technique for Adaptive Blind Decorrelation
Eighth ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing (SNPD 2007), 2007Blind decorrelation is a related task to blind source separation (BSS) which is applicable to numerous problems. A critical challenge in adaptive blind decorrelation (ABD) is the choice of step size to achieve fast initial convergence speed and low steady state error in time-varying systems.

Diffusion Sparse Sign Algorithm with Variable Step-Size
Circuits, Systems, and Signal Processing, 2018In this paper, we propose the diffusion sparse sign algorithm with variable step-size for distributed estimation in sparse and impulsive interference environments. Firstly, we address the problem of in-network distributed estimation for sparse vectors under the impulsive noise environment.
