Complex Autocorrelation??

[Bonhomme]

Hi there,

I have an array of 14,400 complex expressions (X + iY) and I wanted to do a complex autocorrelation on the array. I know there's an autocorrelation VI in LabVIEW, but does it support complex numbers? I have a feeling it doesn't. If not, how would I go about doing this? Thanks.

Hi,
You can calculate autocorrelation of complex array in such a way:
C=X+i*Y - your array
B(C)= - corellation which you want to calculate.

So
B(C)=B(X+i*Y)=

And as a result we have that autocorrelation of (X+i*Y) is equal to the sum of
1. Autocorrelation of X
2. -(Autocorrelation of Y)
3. i*(Crosscorelation of X and Y)
4. i*(Crosscorelation of Y and X)

Good luck.
