Brian, Yes it can!You need to set a decision delay D and then it would operate in a fixed-delay mode, ie, it would spit out a decision at every time instance
with a delay of D compared to the input sample. The survivor matrix (of size DxS) will need to be updated at every time instance in order to make a decision (thus the additional overhead). I am not sure I have the time to code this though.... :-) but it shouldn't be that hard. Achilleas On Wed, 21 Feb 2007, Brian Padalino wrote:
Achilleas, Could the Viterbi block be implemented in such a fashion that the algorithm was a streaming implementation as opposed to a fixed block size? That way, you could just send in a vector of deinterleaved soft decisions, and (with a little bit of overhead) the Viterbi block could take in any variable length block with zero padding at the end. Moreover, it would retain its generic nature but would increase computation by adding a slight overhead. Brian
