Marcus, many thanks again!
It seems that I am on the right way, at least with calculations. :)
Lets continue with your thought-provoking questions.
" Is your received signal real-valued?" No, I put the "complex-to-mag"
block before.
Regarding the final goal.
I would like to evaluate the channel
Hi Roman,
well, it's a short term sample variance, indeed.
Is your received signal real-valued? That's surprising me a bit!
I don't think "variance per packet" is really a meaningful thing to
say. If we're talking proper variance, that's a property of a Random
Variable, not of some short observati
Marcus, great thanks for reply!
Is attached flowgraph a good approach to the variance calculation?
What should I do in case of bursty signals? Can I calculate signal variance
per packet?
Regards,
Roman

You can definitely do that! In fact, it's pretty easy. Really, read the
tutorials I've linked to, and you'll quickly get an idea what to do
when you want a moving average of the power of a signal (namely,
convert it to it's magnitude², then apply a moving average), and once
you have that, it's real
Marcus,
Sorry for confusion, language problem.
I would like to calculate first and second statistical moments (mean and
variance) for received signal level.

Roman

Hi Roman,
probably, it's possible, but I have no idea what you mean with "signal
deviation". Maybe you could elaborate?
To give you a quick look into what GNU Radio can do for you: see https:

Happy signal processing,
Marcus

Hi group,
I would like to evaluate the signal deviation in different propagation
conditions. Is there a way to calculate this in gnuradio or should I export
data for further external processing?
Thanks for replying!
