Abstract :
The paper presents possibilities of an error reduction of the phase estimation with an interpolated discrete Fourier transform (DFT). Properties of interpolations are studied for the rectangular and the Hanning windows with respect to their ability for correction systematic effects. The correction is improved with considering the leakage effect of the component spectrum. Uncertainties of the phase estimations have been studied the simulation and experimental results are presented showing the effectiveness in estimating the phase of the signal component.
