Hi Mailry - I was able to get it run.
I used the "correlate access" block from gnuradio - my installation of
gnuradio didn't like the block in your flowgraph.
And then I had to install the python module "construct" in order to get
the flowgraph to run.
In order to get the flowchart to work - at least in the sense of filling
up the output.txt file - I added a "Stream to Tagged Stream" block and
define a consist tag to get the Tag Debug block to work.
Also, I had to remove the "unpack" block before the PSK modulation,
added a "Unpack K=1" block just after the PSK demodulation - and I set
"Generate Options" to "No Gui" in the Options block.
