Re: How to plot BER vs SNR in GNU Radio

[Barry Duggan]

Farhan,

I don't know much about BER curves, but this example may help you some: 
https://github.com/gnuradio/gnuradio/blob/master/gr-fec/examples/ber_curve_gen.grc

Also search the archives of this newsletter. IIRC, there is a discussion 
about the bus inputs.

Remember to CC discuss-gnuradio in your reply. I forgot on the first 
time for this!

Hello,

I am trying to plot the BER vs Es/N0 using QT Bercurve Sink which has 16 
inputs. But the result is always a constant line and I don't know the 
reason and it is blowing my mind. Also, I don't know whether there is an 
alternative way to plot BER vs SNR. I would really appreciate it if 
anyone could help me in this regard. I just want to plot a simple bit 
error rate curve.

Regards,
Farhan
