I know it may not be possible in the current gnuradio blocks framework,
I am still curious if it can be done.
When I write a signal processing block, the io signature could be
determined by some parameters. It is ok, if these parameters are fixed.
sometimes, especially in the adaptive system, I need to dynamically
these parameter, which result in the updating of io signature of the
blocks. I can make the io_signature to be independent with the dynamic
parameters, but it could be more convenient if the io signature can be
adapted. Of course, it is not easy, as the io signature change could
the upstream and downstream.
Dreams can come true just believe.
