Hi Yang,
the Power of the FFT is only calculated inside the graphical sink, the
connection between the USRP source and the graphical sink represents a
complex sample stream.
I'm still not quite understanding what you really want the USRP to do,
would you mind explaining that again?
Best regards,
Marcus
