Paper title: CHOICE OF THE WINDOW USED IN THE INTERPOLATED DISCRETE FOURIER TRANSFORM METHOD
Author(s): DANIEL BELEGA, DOMINIQUE DALLET, DAN STOICIU,
Abstract: In this paper a criterion for optimal choice of the maximum sidelobe decay window
used in the interpolated discrete Fourier transform (IpDFT) method for estimating the
parameters of a sine-wave is proposed. The window chosen by the proposed criterion is
the window with the lowest order, which ensures that the systematic errors that affect
the sine-wave parameters estimates are very small compared with the quantization
errors. The window is chosen as a function of the maximum sine-wave amplitude up to
which the systematic errors that affect the frequency estimates are very small compared
with the quantization errors. To confirm the effectiveness of the proposed criterion,
some computer simulations and experimental results are presented.
