Re: How to plot BER vs SNR in GNU Radio

[farhan pishe]

Barry, thank you so much for your time, but unfortunately, it wasn't helpful for me and still, I am seeking a way to plot the BER vs SNR. I don't know what is wrong with GNU Radio! Even it doesn't have complete documentation so that I can understand how to do things like this. I hope that someone guides me in a clear way. I want to plot a BER vs SNR for the OFDM simulation which already exists as one of the examples of GNU Radio, but it gives me constant line.

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
