Abstract

Deserving attention to the optimization of algorithm architecture adequacy for polynomial filtering with good numerical stability and convergence speed performances, we propose in this paper an adaptive filtering scheme based on a non iterative orthogonalization polynomials procedure allowing to enhance the performances of a real-time adaptive system. We explore the benefits of generalizing the closed-form expression, derived for optimal NL RF power amplifier identification, to the adaptive identification of audio transmission systems.
