Abstract

Adaptive infinite-duration impulse response (IIR) filters have been studied as a possible alternative to adaptive finite-duration impulse response (FIR) filters. Two of the best known approaches for adaptive IIR filtering include the output error (OE) and the equation error (EE) algorithms. A new algorithm, the so-called composite square error (CSE) algorithm, for adaptive IIR filtering is introduced based on the explicit combination of the OE and and EE schemes. An innovative strategy for updating the composite factor and force the proposed algorithm to converge to the OE solution is also presented. Examples are included to demonstrate some of the interesting features of the new technique
