[Discuss-gnuradio] Initial state options for Viterbi algorithm |

When instantiating a Viterbi decoding block, there are options to
specify what the initial and final states should be or that they are
unknown. This poses no problems if the FEC encoder is initialized
similarly for each block of data. However, when multiple blocks of data
are encoded without resetting the encoder to the same initial state each
time, but instead the encoder remains in the previous final state, there appears to
be no option to set the Viterbi decoder initial state to its previous
final state. As this effectively increases the block size, and therefore
improves performance, it seems that this would be a desirable feature.
Are there any plans to add such a feature or are there other drawbacks
that I may not be aware of?
