is there a specific function (such as MATLAB 'xcorr') you want to
implement?  You can implement 'cconv' with a pair of FFT/IFFT and complex
multiplication.  If you zero-pad and use 2x length FFTs, you can
alternatively obtain linear convolution using an overlap-and-add
configuration.  I haven't looked at 'xcorr' specifically, but my guess is
that you could do what you want with an FFT/IFFT pair.
