Parallel implementations of Turbo decoding has been studied extensively. Traditionally, the number of parallel sub-decoders is limited to maintain acceptable code block error rate performance loss caused by the edge effect of code block division. In addition, the sub-decoders require synchronization to exchange information in the iterative process. In this paper, we propose loosening the synchronization between the sub-decoders to achieve higher utilization of parallel processor resources. Our… CONTINUE READING
