ABSTRACT:
Applying a stopping rule for Turbo decoding for both good and bad code blocks. Terminating decoding, if the iteration either converges or diverges. Generating H-ARQ acknowledgement, using the result of the stopping rule testing. Generating an ACK, if the iteration converges, and generating a NACK, if the iteration diverges. Optionally, dynamically selecting the maximum number of decoding iterations based on MCS levels.
