Re: Modifying BPSK to QPSK

Hi Zachary,

You will have a better chance of getting responses if you post screenshots of your flowgraph instead of attaching grc files themselves. People can't open grc files on their phones or on the go. 

I have not opened your grc files, have you made the proper change to the synchronization technique you are using to account for the change in modulation type from 2 symbols to 4 symbols? That's the first place my mind went that would cause problems.

Hello all,
I am reaching out again as I am trying to modify a working file transmission using BPSK to work using QPSK. I have made all the modifications I believe to be necessary to get the transmission to work with QPSK, however I am unable to see any results. I have debugged this for many hours and am reaching out to see if anyone has any insight. Please let me know if you have any questions, the flowgraphs are attached.

Thanks,
Zach
