That would be great to have with the rise of DSA in the GNU Radio branch. Do you remember who exactly did the demo? Was it "*Software Defined Radio Implementation of SMSE Based Overlay Cognitive Radio<http://cms.comsoc.org/SiteGen/Uploads/Public/Docs_DYSPAN_2010/wright_dyspan_2010.pdf> "
*Their slides appear to have subcarrier suppression in them. Reginald goes to school here, he's part of another wireless group. I will poke him for the code :) - George
