I am working on an application where I have a sender S and a receiver
R. The procesure runs as follows:
(1) S transmits the channel estimation sequence. R estimates channel.
(2) S switches to receiving mode. R switches to the transmiting mode.
R sends the channel estimation back to S.
(3) S switches back to transmiting mode. R switches back to the
receiving mode. S sends data to R.
For both S and R, I created two flow graphs, one for transmiting and
the other for receiving. When switching modes, I was basically
starting and stopping flow graphs. I found that I have to stay in step
(1) and (2) for at least 0.1 sec. Are you aware of any faster method
to do this? Thanks so much for any hint!
