Improved performance of the ML sync (with added computations). It uses the energy calculation to normalize the correlation and the timing sequence and correlation together to determine the timing. This works for frequencies of +-0.6 offset, which is a limiting factor still in the performance but better than the previous checkin....
Mostly fixed the van de Beek ML synchronization scheme. Instead of using the CP timing signal, it correlates against the known preamble just to send along the timing trigger. This works nicely and keeps the frequency more constant in the receiver since it updates the estimate every received symbol. Read the comments inside to see why it's 'mostly fixed' -- this was mostly proving a point for myself today....
Merging ofdm2 branch -r7047:7321 into trunk. This updates the OFDM code to hier_block2 in blks2impl and removed from blksimpl. The new codeimplements a decision feedback sync loop to lock the phase/freq, removes two unnecessary premables and performs frame sync and equalization off...
Remove non-converted OFDM code from blks2impl (examples still use blks, not blks2.)
