Abstract :
The over-determined Yule-Walker equation improves stability and accuracy of the linear prediction analysis. This report describes the effects of introducing over-determined Yule-Walker equation and parameter conversion in the frequency domain into the two-stage ARMA estimation. The simulation results proves that the proposed method is robust against window positioning and retains better analysis accuracy even for noisy cases compared to Cadzow´s method.
