| 摘 要： | 对编码序列之间的相关特性进行了分析研究，将一般的相关概念进行推广，推导出全相关不变定理，揭示了编码序列之间的内在相关机制，更深入地描述了序列之间的相关特性，指出线性变换前后两序列的全相关值恒为1．为探讨序列之间的相关关系提供了一有力工具，尤其是有助于Turbo码中删截矩阵的选取。也为编译码的理论研究和实际应用提供了一个新的方法。

| Abstract: | The general concept of correlation is developed. A new concept of full-correlation is brought forward and used to analyze the correlation features of encoding sequences.It points out the essential principles of the correlation features of correlated sequences,fully describes the logic relations between the sequences, concludes that the value of the full-correlation function of the sequence is equal to 1 before and after the linear transform.These are very useful for the coding theories and applications,as well as for the analysis on the relationships of correlated sequences,especially for the selection of the punctured metrics of Turbo codes. |
