Dear Yang,
My master work is on this topic. I have a recent paper on this which as

N. H. Mahalin.

Yang,
I was talking about benchmark_rx.py, not the transmitter. There is a
callback (sorry, not actually a thread) that sits and waits for a message
from the demod chain called rx_callback. I'm suggesting that you use a
similar technique to send a message about the frequency information, and
then you could use the callback to set the frequency of the device.
I'm also not talking about a simple drop-in replacement for any code that
we
have. We have a lot of examples that will all do various pieces of what
you
want, and you are going to have to synthesize them to make your DSA
application.
Tom
Tom, its very interesting to see and learn your work on DSA. could you
forward this paper to us in the forum? i think the paper is not uploaded
yet. plus, its also great if I can try the code that you have done. is it
open to be download, tested and learned?
we also have a work on parallel sensing and transmit which will eliminate
the sensing time limitation and trade-off. we will published this in a very
near time =) ..
