NI-USRP 2944R. Transmission and reception using labview 2017 (32-bit)

[estefy191]

Hello everyone I am new using the NI USRP 2944R equipment. I am doing a transmission and reception of a 5g Gfdm signal which is done in a matlab script and using labview 2017 (32 bit). I based on a 4QAM transmission to ARM MY BLOCK. At the moment of transimitir my signal I do it correctly but I can not receive my signal transmistida so I can not make my constellation diagram and I have a very high BER I do not know what is due if someone can help me. I do not know if it is necessary to do my programming using labview comunication to get my signal and get a correct BER value and constellation diagram. I would greatly appreciate your help.

How are you sure that you are transmitting correctly? Are you sure you are covering the same bandwidth and the same frequency on the TX and RX?

I believe that if I am transmitting correctly I connect my usrp to an oscilloscope to see if it is correctly transmitting.
The only thing that I see is that the signal that is being transmitted is creating a mirror of the original signal, it is not due to this. As for the frequency if I'm using it both in transmission and in reception.
