A new adaptive recursive delay filter

摘要

An adaptive recursive filter based on a sequential approach of identifying each delay, pole location and coefficient value is proposed. It is observed that if the unknown system to be modeled contains long decaying intervals in its impulse response, this filter has better performance than adaptive FIR (finite impulse response) delay filters or conventional approaches. Its stability monitoring and computational complexity are comparable to the most efficient IIR (infinite impulse response) realizations.
