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 really only building basic math to calculate the
variance :)

GNU Radio comes both with the possibility to interface with SDR
hardware, so that you can assess real-world signals and propagations,
as well as with several channel models that you can use to simulate.
