Running CRC to the signals sent from LabVIEW NXG 5.0 using a USRP

[kabe1]

    I am currently running an experiment where I send a 916.8MHz BPSK signal from a USRP using LabVIEW NXG 5.0. This signal will be received by a pair of Software Defined Radios controlled by MATLAB.

    However, I’m not sure if all the BPSK signals sent from the USRP are received by the SDRs. So, I am trying to do a CRC test against the BPSK signals received, but I’m not sure how to do this.

    I tried using a LabVIEW NXG function called “MLS sequence waveform” where I supposedly could select the maximum number of digits for the binary message before it cycles back to the first digit, but I can’t figure out WHAT the actual binary message is. And because I can’t see what the binary message is, I can’t tell MATLAB what message they are supposed to find.

    If anyone can give me any advice, that will be appreciated!!

P.S. some additional information/details:

1. I have barely touched LabVIEW before.
2. The signal source I am using is something I found from my lab’s database. So, I’m not sure if the signal source is even working correctly.
3. The reason I am suspecting a bit loss in the signal is because there is a filter at the end of the program(diagram), which apparently causes bit loss in a BPSK signal. Not sure why this happens at the moment, but I am trying to see if that is what’s happening in this experiment.
4. The Signals are sent from the USRP to the SDRs via SMA cables (co-axial cables), not wireless.
5. The waveform of the signal source looks like this
6. I'm trying to upload the entire source code(diagram?) as well, but the file is too big to be uploaded.
