Re: [Discuss-gnuradio] bbn 802.11b code compatibility

[Douglas Geiger]

 Of the code found on CGRAN (https://www.cgran.org/), the code in
trunk does not support gnuradio v.3.2. There are two branches on there
that do work though: douggeiger and usrp2_version. The usrp2_version
branch has been getting more work recently. For documentation, I'd
start just by looking at the python code (examples/*.py). There are
some emails floating around if you search google - but the final word
is the code.
 To get you started, the general format of the receiver goes something like:
 USRP ---> Matched Filter ---> Bit Sync -----> Demodulate ------> Deframe
                 FIR (barker-11)      bbn.slicer     bbn.dpsk.demod
  bbn.plcp

The transmit side has a similar structure - but it only work with the
USRP2 (if you want interoperability with other wifi devices that is) -
in which case you should be focusing on the usrp2_version branch.  My
branch probably does not transmit correctly.
