Abstract
In this paper, a VLSI architecture of turbo decoder employing an efficient stopping criterion is proposed. The new stopping criterion algorithm is based on Hard Decision Aided(HDA) stopping criterion algorithm, using phase estimation method to reduce iterations also improve turbo decoding efficiency. In high SNR environment, the proposed algorithm requires less iterations without losing error correction ability compared to traditional stop criteria algorithms. In addition, it can save power consumption due to decoding termination within single iteration. As for low SNR environment, we can stop iteration immediately when it detect the
