For small constellations, you can just specify the points manually.
Here's an example for 16QAM. Just paste into the "Symbol Table" field in
the block properties. The dimension is 1.
[complex(3,3), complex(3,1), complex(1,3), complex(1,1), complex(3,-3),
complex(3,-1), complex(1,-3), complex(1
Dear Nur,
it would be very helpful if you could wrap you console output into one or two
sentences describing what you did.
I have no idea where the error message comes from and would suggest you go to
/home/user/gr-ieee802-11/ and do a
git reset --hard
then open examples/wifi_phy_hier.grc and
Hello,
How can I specify symbol table and dimension for QAM in chunks_to_symbol
block? which modulation is indicating in fsm_utils.py by orth2 orth4?
Can anybody help me. I am new to this GnuRadio.
ThankYou
With Regards,

Hi Nur,
the actual error message is not shown in your output. I think you should run
the flow graph in gdb with something like
gbd python
gdb-prompt> run /home/user/gr-ieee802-11/examples/wifi_loopback.py
once you hit the error
gdb-prompt> bt

Hi,
I have worked my way through the Guided Tutorials on gnuradio.org. I have
written OOT blocks in Python and managed to expose some set methods in the
block as callbacks. Now I have written an OOT C++ block sweeper_cpp_f and I
want to expose a couple of setter methods in my block's class as
Are you referring to blocks? If so, see
https://gnuradio.org/redmine/projects/gnuradio/wiki/Move_3-6_to_3-7 There's
a script there that will convert some GRC files, and if you don't want the
script it at least shows the name mapping in an explicit format.

Hi,
I am trying to migrate an OOT module written in 2010 to 3.7. I think (hope)
that the final hurdle to achieving this is having to deal with
gr_complex_to_xxx that was removed in 3.7 but which is referenced in the
code.
I have searched in vain to find out what gr_complex_to_xxx did or how to

Hi Marcus,
Thanks for your extensive reply. From your reply I am not sure if you
understood that I am not doning anything graphical in work(). In very
