[Discuss-gnuradio] Transmitting 2 dbpsk signals

[Maduike, Dumezie]

Hello everyone,

I am trying to transmit simultaneously from two USRPs using 'benchmark_tx.py' 
to a third one acting as a relay with 'benchmark_rx.py' running.  Do the python 
scripts on the receiver's end such as 'pkt.py' use the access codes to 
determine which type of modulation scheme the transmitters are running or is 
there a different method in determining which type of mod scheme is used?

Also, when the two signals from the transmitting USRPs are sent to the relay 
USRP, are the two signal phases automatically aligned or is this done somewhere 
else in the ['dbpsk.py' or 'dqpsk.py', etc.] files?

Thanks in advance!
