摘要

This paper presents a VSS-LMS adaptive algorithm that updates the step-size parameter taking into consideration the input signal power and the average residual error. That is the step-size parameter will have a local component (for each filter coefficient and given by the input signal power and a global component (given by the average of the residual error). The adaptive filter performance is significantly improved.
