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。
提齣瞭一種新的Turbo碼的聯閤譯碼算法,該算法結閤瞭常數Log-MAP譯碼算法和Log-MAP算法的優點,併且結閤瞭停止判決準則。新算法在效率和糾錯性能上達到瞭較好的平衡,尤其是在中高信譟比的情況下:隻增加瞭較少的計算量,就使得常數Log-MAP算法達到瞭幾乎Log-MAP算法的糾錯性能。

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 .
