Hello.
I am a graduate student researcher with the Satellite Technology Lab at The University of Texas at Arlington.
I've
been trying to find out the working behind the USRP source block. I did
find some basic description (like what it does in a few sentences and
the arguments it accepts) in the GNU radio documentation but could not
find detailed information. My queries include the following:
1: How exactly does the USRP source block process an incoming
signal? Meaning, what kind of signal processing techniques does it use?
2: What kind of sampling techniques does the USRP block use on the incoming signal?
