The USRP is a piece of h/w that along with software can do an extremely wide range of tasks. The USRP itself (and GNU Radio for that matter) doesn't adopt any particular spectrum sensing method. You are free to make up and implement whatever you like. > I know that there are such spectrum sensing methods at present to > determine which spectrum has been occupied by primary user: Matched Filter > Detection, Energy Detection, Cyclostationary Feature Detection, and > Interference Temperature, > I read through the file usrp_spectrum_sense.py in directory > "gnuradio-3.1.2/gnuradio-examples/python/usrp", but I didn't find the > answer. usrp_spectrum_sense show one way that you could step across the spectrum and make measurements.
