Thanks for confirming. I believe that IT++ version will work with
corresponding GNU Radio version.

Also what do you think (since you have developed the code for long time :)
) : IT++ version will be as efficient as the current one? I mean the
current version uses SIMD for Viterbi.

I have tested the current version for success rate. I can share the
results(attached). Success rate mentioned is nothing but ratio of received
to transmitted frame per second using a R&H VSG. The test was done over the
air.
