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?
