A further consideration for porting applications/examples that "know" that they're talking to a USRP1 is that UHD uses a range of {-1.0,+1.0} for complex_float data streams, and internally scales that to whatever is appropriate for the hardware. There are plenty of apps out there that "know" that the data should be in {-32767,+32768}, and they will end end producing clipping in UHD unless theYou will have to change the block that is instantiated to be a uhd usrp source or sink. There is no reason that rest of your modulation/demodulation chain or mac layer would have to change. Cheers, -Josh
data are re-scaled.
