2008-01-02Merging ofdm2 branch -r7047:7321 into trunk. This updates the OFDM code to ↵trondeau
hier_block2 in blks2impl and removed from blksimpl. The new code implements a decision feedback sync loop to lock the phase/freq, removes two unnecessary premables and performs frame sync and equalization off single preamble symbol. Also adds/updates Python plotting tools and a branchless clip algorithm in gr_math.h. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@7324 221aa14e-8319-0410-a670-987f0aec2ac5
