On orthogonal parallel realization for adaptive IIR filters

Juan Cousseau, Guillermo B. Sentoni, Paulo S. R. Diniz, Osvaldo Enrique Agamennoni

Open publisher page 4 citations

Abstract

A new parallel realization is proposed to implement adaptive IIR filters. This realization introduces several improvements to a previously proposed approach using discrete orthogonal functions. The new adaptive IIR filter realization has lower computational complexity than the standard parallel realization. A discussion regarding their properties and convergence speed is also included. In order to illustrate the performance improvements, some simulations results are included in the system identification application.
