Circular Cross Correlation using FFT
Version 1.0.0.0 (1.69 KB) by
Johannes Schmitz
Calculate the circular and non-circular cross correlation using the FFT method.
Rough idea:
Get the crosscorrelation of two vectors a and b by:
e = fft(c);
f = fft(d);
g = e.*conj(f);
h = ifft(g);
See code for complete version and details like zeropadding.
