Abstract

This article solves the optimal weighted least mean square (WLMS) filter design problem using sums of separable filters as a sequence of separable filter approximations. An efficient computational algorithm based on necessary conditions is presented. The procedure requires neither the solution of the unconstrained WLMS problem nor the singular value analysis of the ideal filter
