| | | | | | | | | | | 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

| | | | | | | | | | | | | | | | This includes: * renaming gnuradio-examples/python/gmsk2 to gnuradio-examples/python/digital * refactoring the digital data tx and rx test code into benchmark_tx and benchmark_rx. These accept a -m <modulation> argument. <modulation> can currently be selected from gmsk, dbpsk, dqpsk * Two new AGC blocks: gr_agc2: separate attack and delay rates; gr_feedforward_agc: FIR-ish compressor. Normalizes to peak envelope. * Working DBPSK mod/demod (works fine) * Working DQPSK mod/demod (works, but still needs more work) git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@3662 221aa14e-8319-0410-a670-987f0aec2ac5
