I have implemented an OFDM transmitter and receiver using USRPs X300 and GNURadio. The implementation works fine and signal was received successfully by the receiver. Now, I am trying to record the I/Q samples of the signal received by the usrp receiver using File Sink (file.dat) as shown in Figure Receiver. But that did not work. Anyone has done that before?
(The data recording will be used later for offline signal processing)
