You're in luck - I just back back from some traveling, and have
managed to gather up a patch. However - this is a patch to the
version from the U of Utah, SPAN Lab version (http://span.ece.utah.edu/pmwiki/pmwiki.php?n=Main.80211bReceiver
) - which does the despreading in the FPGA (which therefore disables
that part of the flowgraph in the python code). So if you want a
patch versus the original BBN code, you'll need to back those
changes out (maybe doing a reverse patch from the Utah version?). In
any event, I'll have time in the next few weeks to return to this,
if you need help figuring out what I did (the hier2 conversion
wasn't too complicated).
The unified diff is attached.
