Arrr. I meant:

Cross-correlation in the time domain is the same as ordinary product by 
conjugate in the frequency domain.

PS: Similarly, cross-correlation in the frequency domain is the same as 
ordinary product by conjugate in the time domain. (due to the Fourier 
transform being almost its own inverse)

BTW some people (or a lot of people) may write conj(A)*B instead of 
A*conj(B). This doesn't yield the same result, but still, the two results 
are conjugates of each other.
