Normalized Least-Mean-Square Algorithm with a Pseudo-Fractional Number of Orthogonal Correction Factors

Sang Mok Jung, Ji-Hye Seo, and Poo Gyeon Park

Abstract—This paper proposes a normalized LMS algorithm (NLMS) that automatically determines the number of orthogonal correction factors (OCFs) by using a pseudo-fractional method, which relaxes the constraint that the number of OCFs in the NLMS algorithm must be integral and introduces the concept of a pseudo-fractional OCF number in the adaptation rule. The pseudo-fractional OCF number is adjusted by using the difference between the averages of the accumulated squared-output errors. The experimental results show that the proposed algorithm has not only a fast convergence rate but also a small steady-state estimation error with low computational complexity in comparison to existing algorithms with multiple input vectors.

Index Terms—Adaptive filters, normalized LMS with orthogonal correction factors (NLMS-OCF), pseudo-fractional OCF number, pseudo-fractional method.
