Viterbi blocks have erroneous input type in grc


#1

Josh,

All viterbi blocks in gr-trellis (except viterbi_combined) have input
floats and output X (see the template in
gr-trellis/src/lib/trellis_viterbi_X.cc.t).

However, in grc they appear to have the same input as the output.

Thanks
Achilleas

I fixed metrics_x and viterbi_x, what else was wrong? What do you think
about adding a trellis examples directory in the grc examples? -Josh

Josh,

I committed a nice little example that uses grc and gr-trellis:
(it is an example of interference cancellation in a multi-user system).

It is in grc/examples/trellis.
Could you please make the appropriate modifications in the
makefiles/config files; don’t know how to do that yet…

thanks,
Achilleas
