Interpolated fft
WebSpectral Interpolation The need for spectral interpolation comes up in many situations. For example, we always use the DFT in practice, while conceptually we often prefer the DTFT.For time-limited signals, that is, signals which are zero outside some finite range, the DTFT can be computed from the DFT via spectral interpolation.Conversely, the DTFT … WebAbstractHow to accurately compensate the Doppler shift is the main challenge for broadband satellite terminals. In this paper, a frequency offset estimation algorithm based on frequency domain window function iterative peaking search is proposed with high-...

WebPeak Detection (Steps 3 and 4) Due to the sampled nature of spectra obtained using the STFT, each peak (location and height) found by finding the maximum-magnitude frequency bin is only accurate to within half a bin.A bin represents a frequency interval of Hz, where is the FFT size. Zero-padding increases the number of FFT bins per Hz and thus increases …
