By analyzing the second-order and fourth-order IIR filter that affect the variance adaptive prove second-order IIR model has a single peak characteristics, to achieve stable convergence; while the higher-order IIR model polymorphic, so the need for the estimated parameters are initialized conclusions. Proposed use of FFT frequency estimation assisted IIR adaptive filter to achieve more frequent rate estimation, parameter estimation for the multi-point frequencies adaptive selection process provides a theoretical basis.
