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 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?
