If the length of the encoded bit stream is L in , and reset? is set to TRUE, the Viterbi decoding algorithm (for a rate k/n code) returns a total of L out = k×[floor(L in /n)-D] decoded bits in a single iteration, implying that a total of k×D message bits are buffered inside the node. To recover the entire message of length k×floor[L in /n] in a single call to MT Convolutional Decoder with reset? set to TRUE, choose one of the following options:
Append max(D,K-1)×k zeros to the end of the message prior to performing convolutional encoding. Here k represents the message word length.
Append D×n zeros to the end of the encoded bit stream prior to calling MT Convolutional Decoder. Here, D is the traceback depth employed in the convolutional decoder, and n is the code word length.
