A variable step size LMS algorithm
IEEE Transactions on Signal Processing, 1992A least-mean-square (LMS) adaptive filter with a variable step size is introduced. The step size increases or decreases as the mean-square error increases or decreases, allowing the adaptive filter to track changes in the system as well as produce a small steady state error. The convergence and steady-state behavior of the algorithm are analyzed.

The convex variable step-size (CVSS) algorithm
IEEE Signal Processing Letters, 2000 This letter introduces the convex variable step-size (CVSS) algorithm. The convexity of the resulting cost function is guaranteed. Simulations presented show that with the proposed algorithm, we obtain similar results, as with the VSS algorithm in initial convergence, while there are potential performance gains when abrupt changes occur.

Variable Step-Size Sign Subband Adaptive Filter
IEEE Signal Processing Letters, 2013 This letter proposes a variable step-size sign subband adaptive filter (SSAF) based on the minimization of mean-square deviation (MSD). In the process of minimizing the MSD, because it is not feasible to know the exact value of the MSD, the step size is derived by minimizing the upper bound of the MSD in each iteration. The proposed algorithm uses this

A Variable Step Size for Normalized Subband Adaptive Filters
IEEE Signal Processing Letters, 2012 A normalized subband adaptive filter algorithm uses a fixed step size, which is chosen as a trade-off between the steady-state error and the convergence rate. In this letter, a variable step size for normalized subband adaptive filters is derived by minimizing the mean-square deviation between the optimal weight vector and the estimated weight vector ...

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].
