Hi every1, i would like to see the performance of a system BDPK. I saw  
in  
the gnu web page (  
[http://gnuradio.org/redmine/projects/gnuradio/wiki/Simulations](http://gnuradio.org/redmine/projects/gnuradio/wiki/Simulations) )one  
graphic, in which could see the BER VS EBNO. i want to get that graphic.  
my doubt is where should i put the variable slider “ebno” .  
regards.  
Lucas.

Hi Lucas,  
that graphic was generated using the python file that is linked to  
directly above the graphic, and not by adjusting some slider.  
I think you should really read that source code, it will bring a lot of  
insight into the problem at hand.

Best regards,
