| Abstract(in English) | Due to its simplicity and accuracy, quadratic peak interpolation in a zero-padded Discrete Fourier Transform (FFT) has been widely used for sinusoidal parameter estimation in audio applications. While general criteria can guide the choice of window type, FFT length, and zero-padding factor, it is sometimes desirable in practice to know more precisely the requirements for achieving a prescribed error bound. In this paper, we theoretically predict and numerically confirm the errors associated with various parameter choices, and provide precise criteria for designing the estimator. Noise robustness of the estimator is also discussed. |
