Hello, I am trying to add the ability to de-puncture to my viterbi decoder, but I am unsure of how to determine where to insert my "don't care" bits. If I have received a stream of bits that are encoded, how is it possible to find the proper location to place the bits that were punctured out at the encoder? I have thought of using an initial block of data and testing different offsets, using the offset with the smallest associated metric. This seems wasteful though. Any suggestions?
