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.

Hi,
you are right. The current implementation does not use soft-bits but
feeds hard bits into the decoder.
In 2013, I used the soft-input Viterbi decoder from the IT++ library.

Hi,
I am doing some proof of concept using gr-ieee 802.11.
The paper by author [1] says that it uses softbits, however in
the method
*constellation::decision_maker(const gr_complex *sample)*, I see
outputs as hardbits.
Am I missing something here i.e. any particular commit or branch
where the softbits implementation is there.
Its very important for my algorithm to use softbits :-/
