For an example on how to do that with two convolutionally encoded
transmissions look at the GRC example in:
We’ve just got two USRPs in our lab and we want to start using them to
do some demodulation.
I’d like to use one of them to transmit the sum of two (uncoded)
signals, useful and interference, with possible relative scaling to
simulate different channels. At the receiver side, I wanna then
implement different demodulators, like treating interference as noise
or successive demodulation (demodulate interference, cancel and
Is there any reference I could take a look on how to implement this in
USRP? Many thanks!
