Abstract

In this paper, we provide a mean square analysis of the M-max NLMS (MMNLMS) adaptive algorithm introduced in Aboulnasr and Mayyas (1996). The algorithm selects, at each iteration, a specified number of coefficients that provide the largest reduction in the error. It is shown that while the MMNLMS algorithm reduces the complexity of the adaptive filter, it maintains the closest performance to the full update NLMS filter for a given number of updates. The stability of the algorithm is shown to be guaranteed for the extreme case of only one update/iteration. Analysis of the MSE convergence and steady state performance for i.i.d. signals is also provided for that extreme case
