Thanks Martin, I'll try that and also I don't happen to see any Inverse FFT
blocks on Gnu-radio, is there a way I can do the IFFT on GNU-radio since there
is no block for it?
The FFT block has a parameter that says "Forward" or "Reverse" (or
Inverse).

Hello,
I'm trying to find a way that I could cross-correlate two FFT signals
that I have coming in from two UDP networks, anyone know of a block I
can do that with?
There's no dedicated xcorr-block, but you can do a fast correlation using FFTs
and point-wise multiplication.

Thanks in advance, Marcus
