-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey all,
I have some updates for you too. After some evaluations with my mentors, I started from scratch and wrote my own OOT module gr-celec which now contains a working rate 1/n Viterbi Decoder which can have as many states as it wants. If it has more than 8 it can also use SSE kernels :D Results are far better than my efforts to speed up the existing gr-trellis. Complex full euclidean branch metrics with SSE4.1 are approx 4x faster than the generic kernels, and Viterbi Path Update kernels with SSE4.1 are approx 3x faster than the generic ones. I am quite satisfied with these results. You can learn a bit more about it on my blog http://spectrejan.blogspot.de/ Now I have to do some cosmetics to gr-trellis/examples and then start on the Log-MAP Decoder.
