Sorry, but your question is not very clear. It's a wireless modem, which
means it's subject to all sorts of issues that are dependent on your
setup and parameters.

The best thing to do is to start simple and use usrp_fft.py to see if
you can observe any signal at the receiver and that the signal has a
good SNR. If you have the qtgui package installed with GNU Radio, you
can also try to use benchmark_qt_rx.py which will show you the received
signal and the baseband symbols (so you can look at the constellation).
