Newbie here. I have some questions regarding the example programs under
gnuradio-examples/python/digital-bert. I just ran a link and swept my
power. I recorded the estimated snr and ber and I’m trying to plot them
verify things are working properly. Is the SNR estimation done at
or passband? When I plot the theoretical BPSK snr vs. ber curve, there’s
significant offset between my experimental data and theoretical plot
yes, I’m ignoring SNR values below 7 dB). Also, a more basic question is
what is the best method to find documentation for the code? The class
documentation under the wiki seems rather overwhelming and I have a hard
time finding what I need.
My second question is how the BER is calculated? I’m seeing values <
But this is entirely unreasonable, as I’d have to be sending > 100 gb of
data to be getting a BER close to that value. Looking at the code, its
clear to me over what packet size the BER is calculated and what the
BER confidence value should be.
Thanks for any help that can be offered.
