Dear all

I try to transmit Audio File using simple DQPSK modulation and  N2910 USB support USRP. I  can transmit a clear audio file, but the second USRP does not synchronize and receive the audio file. I tried  all possible sample rate and center frequency according to  USRP manual but still, the same it received only some kind of noise staff  please  tell me if I made a mistake







Thank you
