We investigate the convergence behavior of the normalized least mean square (NLMS) algorithm in the structure of a linear transversal filter. At the n-th iteration, the traditional NLMS transversal filter generates the n-th output signal by using linear convolution of the n-th input vector and the n-th coefficient vector. Based on this result, the n-th coefficient vector is updated to the n+1-th coefficient vector. We attempt a refined filtering (RF) approach to the NLMS transversal filter, to generate another output signal by linear convolution of the n-th input vector and the n+1-th coefficient vector. Theoretical analysis and computer simulation demonstrate the effectiveness of the RF technique.
