I'm assuming you want to visualize the symbols after synchronization but before decision making. At the moment this is a pain, because the fine phase adjustment and the decision making are performed in the same block (constellation_receiver). What you want is the fourth optional output of the constellation_receiver block. Unfortunately this output is not available in any of the hierarchical demodulation blocks (because hierarchical blocks can't have optional outputs yet). This means that if you want to do it in grc you won't be able to use one of the straightforward demodulation blocks, rather you'll have to put all the synchronization blocks in there independently.
When I want to do this, I do it in python, and hackishly connect directly to the 'constellation_receiver' block that is inside the demodulation block. i.e. tb.connect( (my_demodulation_block.receiver, 4), my_visualization_block) Ben On Fri, Mar 22, 2013 at 2:53 AM, Azza Ben Mosbah <azza.ben.mos...@gmail.com> wrote: > Hello, > > I receive data from USRP and demodulate them, then I can have the > constellation.
