| Abstract(in English) | As a means of eliminating plural narrow band signals embedded into broad band signal, ADF which is constructed of parallel connected second order IIR filter, has been proposed. Each of second order IIR filter estimates each narrow band signal. In this paper we study the improvement of convergence characteristic of the ADF equipped with the pole angle control algorithm. In the conventional algorithm we use the converged value of the filter coefficient which gives the zero position, hence time (input signal number) for renewal of pole angle is large. In the proposed method by adapting the pole angle iteratively for each input signal without waiting the converged value of the filter coefficient, the convergence characteristics is improved remarkably. The above facts if confirmed by simulation results. characteristics |
