S/N ratio vs BER reference?

GNU Radio
1

Hi All,

I’m playing around with digital modulation techniques in GnuRadio and
would like to get a sense of how successful my efforts are in terms of
BER vs. S/N ratio.

Can someone suggest a reference that provides BER vs S/N ratio curves
for some of the common encoding approaches?

Thanks,

-Greg

Hey Greg,

I’ve been working on a tool to do this over the air. I’ve been testing
it
in an anechoic chamber, and haven’t quite gotten the performance where I
think it’s off-the-shelf ready (it also includes a couple of custom
blocks); there’s still some synchronization issues I need to think about
(it’s my first real radio system). If no one else pops up with ideas I
can
share what I’ve done so far.

Hi Gregory,

not sure if this is what you want, but have you checked
gr-digital/examples/berawgn.py?

Also, perhaps you want to read
