I want to implement MIMO using gnuradio.
I already could do differential and coherent(BPSK) communication link
between two USRPs( daughter board Flex 2400 ).
right now for channel estimation in MIMO I need to do reconfigure flow
graph. As mentioned in
www.gnuradio.org/trac/wiki/Tutorials/WritePythonApplications
after fg.stop() I call fg.wait() and then reconfigure flow graph, as bellow
...
fg.stop()
fg.wait() #reconfigure flow graph
print "hello"
fg.disconnect(fg.amp, fg.u)
self.subdev[0].set_enable(False)
self.subdev[1].set_enable(True)
fg.connect(fg.amp, fg.u)
fg.start()
...
but code waits in gt.wait() and never goes ahead(never prints "hello").
what shall I do to fix it?
thanks,
Mehdi
