Haven't had time to check, but: Do you do (a) absolute phase recovery and (b) framing, so
that you know (a) how to resolve the ambiguity do to unknown phase of the channel and the
symmetry of the constellation diagram and (b) what bit is the first?
Best regards,

Hello all,
I have been working on creating a QAM-16 transmitter in GNURadios. We observed that the
output at the very end of the flow does not look like the input, and we wondered if all
the blocks are properly configured. Please note that before you run it, you should
configure the file paths to your computer as the path is local to my computer.
The file for the flow diagram is attached below.
Thank you.
