There is a very fast (SSE,SSE2) viterbi decoder by Phil Karns.

I have a trellis encoder and the V decoder is in debugging (by me) -

Well, (this is a boy trying a grown-ups job ;) I managed to get
two new modules to compile in gr-atsc, atsc_interleaver and

(and accounting for atsci_reed_solomon having one class
and two methods(?) encode and decode, whereas
