| 摘 要： | 分析了Ｔｕｒｂｏ码编译码对交织器相关性的要求，以及交织器的设计对码距的影响，提出了以序列相关性作为设计交织器的判据和斜对角交织方案。得出了当采用斜对角交织时，由于其序列相关性为０，在较小的交织深度下，Ｔｕｒｂｏ码可取得较好的差错纠错性能，仿真实验证明了此结论。

| Abstract: | From the requests of Turbo-codes' coding and decoding, interleaver's relativity is discussed, and the performance of interleaver design affecting the hamming distance of Turbo-codes is analyzed. Relativity is proposed as a criterion. Based on the criterion, a new interleaving method of inverse diagonal is introduced. Because the relative coefficient of new method is zero and the length of interleaving is short, Turbo-codes can get satisfying error correcting. The conclusion is proved by simulation. |
