Interpolated dft
WebAbstractHow to accurately compensate the Doppler shift is the main challenge for broadband satellite terminals. In this paper, a frequency offset estimation algorithm … Webunder SSO. An interpolated-DFT method is then proposed in Section IV-A to estimate the damping factor and frequency. Note the conventional interpolated DFT is developed for the real-number waveform data [13], [14]. It is modified in this paper to deal with the complex-number synchrophasors. Afterwards, a Hann-window based DFT analysis is further

WebWindowed interpolated discrete Fourier transform (DFT) has been well-studied to deal with the spectral leakage and picket fence effects in frequency estimation. When the number … WebInterpolated points, returned as a vector, matrix, or multidimensional array. If length(X,dim) = m, and X has a sampling interval of dx, then the new sampling interval for y is dy = dx*m/n, where n > m.. If dim is specified, then interpft pads or truncates X to length n in dimension dim, so that size(y,dim) = n.
WebSep 1, 2016 · The paper presents a new application of the Bertocco-Yoshida order 1 (BY1) interpolated discrete Fourier transform (IpDFT) with leakage correction (LC) to analysis of nuclear magnetic resonance (NMR) signals. It is shown how the BY-LC IpDFT algorithm can be used for NMR spectrum quantification, i.e. 1) estimation of frequencies, damping … WebH. Wen, C. Li and L.
