Stochastic Behaviour Analysis of Adaptive Averaging Step-size Sign Normalised Hammerstein Spline Adaptive Filtering

by Theerayod Wiangtong, Sethakarn Prongnuch and Suchada Sitjongsataporn

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 1, Page # 577–586, 2021; DOI: 10.25046/aj060162

Abstract:

We introduce a sign algorithm based on the normalised least mean square with Hammerstein adaptive filtering using adaptive averaging step-size mechanism, which is derived by the minimised absolute a posteriori squared error. To improve the performance by reducing computational complexity, we suggest an adaptive averaging using energy of errors to update step-size variant. The analysis…

Performance Analysis and Enhancement of Spline Adaptive Filtering based on Adaptive Step-size Variable Leaky Least Mean Square Algorithm

by Sethakarn Prongnuch and Suchada Sitjongsataporn

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 6, Page # 642–651, 2020; DOI: 10.25046/aj050678

Abstract:

This paper presents an adaptive step-size and variable leaky least mean square algorithm based on nonlinear adaptive filter with the adaptive lookup table using spline interpolation. An adaptive step-size approach is proposed with the energy of squared previous and present errors to boost up the convergence rate. A modified variable leaky mechanism is proposed with…
