Thank you Eric,
I found the lock/unlock function can work only in benchmark_ofdm_rx.py.
When I use them to change the graph or even not change any thing with 
benchmark_ofdm_tx.py, the transmitting just stopped. No packets can be 
received although the transmitter is still printing out "."
I cannot find out what's wrong with it, do you?
Thanks a lot.

Best regards,
Yan Wang
