Abstract

A unimodal stable adaptive recursive filter is introduced. The forward and the backward coefficients are jointly optimized such that two different performance indices are minimized. The performance criteria are quadratic functions of the filter coefficients. Moreover, the filter stability is always hyperstable during the adaptation process. This filter has less complexity than the direct form structure.
