Hello all,
I have USRP B210 and I am using it with Labview. I am simulating niUSRP EX PSK Tx/Rx.vi examples. I have also used MT Calculate BER.vi block to calculate BER of PN sequences. I am using BPSK and using 6 samples per symbol. The problem is that my BER output is switching 1 and 0 when the reset switch is True. I think it should be 0 or close to zero. it is showing zero but I dont know why it is showing 1 sometimes.
Another problem is that if use 8 samples per symbol BER is always 1.
I also want an example program for detecting PN sequence on Rx side, I am using cross correlation technique but I am not getting the correct results.
Thank you.

Hi aster_yeyo,
What trigger threshold and confidence are you using for the MT Calculate BER.vi?
