On time delay estimation using an fir filter

Web1 de ago. de 2024 · Estimation of the time delay of a passive sonar system in a reverberant environment is one of the most challenging tasks. For some decades, the well-known generalised cross-correlation (GCC) method has been implemented to estimate the time delay. By using various pre-filters in the GCC method, the quality of TDE has … Web3 de set. de 2024 · So just to be super clear, the process is: Take the FFT. Construct the phase shift e − 2 π i k D N + π i D (where k=sample number, D=time shift in samples, N=sample length of the FFT) Do FFTshift on the phase shift coefficients calculated in #2. Now multiply the FFT data with the phase shift coefficients. Do the IFFT.
