If you specify a scalar for WINDOW, SPECGRAM uses a % Hanning window of that length. WINDOW must have length smaller than % or equal to NFFT and greater than NOVERLAP. NOVERLAP is the number of % samples the sections of A overlap. WebAs K increases, the channels become flatter, resulting in a weaker entropy and hence, in a lower SKR. Figure 6.

WebFeb 10, 2024 · Another explanation for ‘NFFT’ in the documentation for the fft (link) function is that it is the length of the signal you want to calculate the Fourier transform of. (It zero-pads the time-domain vector before calculating the transform.) Because of the nature of the fft algorithm, this is usually 2^n, where ‘n’ is any integer, because it makes the algorithm …
