This paper proposes a modification to extrapolated LMS algorithm proposed in [6] to guarantee consistent improved convergence speed. Unlike the original extrapolated LMS algorithm that exhibits improved performance on specific runs but is not guaranteed to perform well at any given run, the proposed algorithm is based on the repeated application of the extrapolation process in a way that allows the algorithm to retain the ELMS advantage for any arbitrary run with limited additional complexity.
