Tim, thanks for the contribution. At this point I am gnuradio-less since my hard disk failed a couple of days ago... but I'll test all the uploaded code as soon as I am up and running.
Thanks again, Achilleas Tim Meehan wrote:
Achilleas and Eric, I have attached a patch to trellis_viterbi_X.cc.t, trellis_viterbi_X.i.t and trellis_viterbi_X.h.t This patch allows for multiple initial and/or final states by calling viterbi with a vector for S0 and/or SK. The call is overloaded so that viterbi can still be called with a scalar. The two accessor methods for d_S0 and d_SK still work for scalars but just return the first element if S0 or SK are vectors. I was not sure how to overload this based on return type. I would be happy to write a patch for the test code qa_trellis.py but it does not seem to have a test for viterbi right now. I would also be happy to write a patch for the documentation gr_trellis.xml (was this written by hand or machine generated?) I don't think there was any bounds checking for the scalar call with S0 and SK so I did not add any for the vector call. i.e. you can call viterbi with a value for SK that is greater than the number of states.
