Evolutionary Digital Filtering for IIR Adaptive Digital Filters Based on the Cloning and Mating Reproduction

摘要

In this paper, we compare the performance of evolutionary digitalfilters (EDFs) for IIR adaptive digital fil- ters (ADFs) in terms ofconvergence behavior and stability, and discuss their advantages. Theauthors have already proposed the EDF which is controlled by adaptivealgorithm based on the evolutionary strategies of living things. Thisadaptive algorithm of the EDF controls and changes the coefficientsof inner digital filters using the cloning method or the matingmethod. Thus, the adaptive algorithm of the EDF is of a non-gradientand multi- point search type.
