一种新的联合Turbo译码算法

摘要

This paper proposes a novel Turbo decoding algorithm. This new decoding algorithm combines the constant Log-MAP decoding algorithm,Log-MAP decoding algorithm and stopping criterion . With the same computational complexity,this novel decoding algorithm is superior in terms of bit error rate per-formance than the constant Log-MAP decoding algorithm .%提出了一种新的Turbo码的联合译码算法，该算法结合了常数Log-MAP译码算法和Log-MAP算法的优点，并且结合了停止判决准则。新算法在效率和纠错性能上达到了较好的平衡，尤其是在中高信噪比的情况下：只增加了较少的计算量，就使得常数Log-MAP算法达到了几乎Log-MAP算法的纠错性能。
