Abstract

This paper proposes a fast convergence algorithm for L2- sensitivity minimization problem of two-dimensional (2-D) separable-denominator state-space digital filters subject to L2 -scaling constraints. The proposed algorithm reduces a constrained optimization problem to an unconstrained optimization problem by appropriate variable transformation, and minimizes the L2 -sensitivity by iterative calculation called successive substitution method. Our novel algorithm can achieve the L 2-sensitivity minimization with quite fast convergence behavior.
