If your computer is arbitrarily fast: the maximum sampling rate you can get out of the USRP.Hello Everyone, I am interested in developing broadband applications (~30MHZ BW) using the USRP and I have some questions: 0) What is the largest bandwidth I can process using a flow graph with relatively large complexity (e.g. 16QAM demodulator simple lowpass, 2 x mixers), any USRP and a computer with arbitrarily large processing power. I just want a rule of thumb approximation.
That would be something like 25MHz for N200/N210 @16bit, 50MHz @8bit, 200MHz out of the X300/X310,
and something mainly depending on your USB3 controller for the B200/B210.
Yes, but in Matlab they will only be offline processing applications.1) I know it's probably not the right place to ask, but do you think my application can be implemented in either Labview, or MATLAB USRP interfaces?
Yes, there are :)3) Are there any papers/applications notes etc in the literature that you are aware of that implement broadband (30 MHZ BW) systems using the USRP?
This one is not involving GNU Radio, but it's impressive nevertheless, since it's 128 times a 30.72MHz sampling rate.
Then there's a load of papers you'll find when searching IEEE Xplore for "USRP gnuradio", and one of the nice things about GNU Radio (as much as about the USRPs) is that sample rate is just a setting -- if you can set the desired sample rate, and your algorithms can deal with that rate, you're fine.
There's inherently high demand for bandwidth in radar applications , so choosing radar as a topic is a good approach for finding papers describing USRP usage at high sample rates.
