Resumo
This paper presents the adaptive IIR filtering with a parallel form realization in a system identification application using a prefiltering algorithm and distinct initialization for each section of the parallel filter. The frequency domain implementation and a recursive frequency sampling structure was used in computer simulation and the results present gains in convergence speed and in the stability of the adaptive filtering.
