基于交织和完备序列的零相关区序列集构造方法

Construction Method for Zero Correlation Zone Sequence Set Based on Interleaving Technique and Perfect Sequence

提出新的基于交织技术和完备序列的零相关区序列集的构造方法。首先通过级联、交织方法生成了完备零相关区序列,然后基于交织技术利用完备序列和零相关区序列集构造了新的零相关区序列集。构造过程中,通过利用零相关区序列集代替正交矩阵,能使目标序列集的周期长度和零相关区长度都得到扩展。该构造方法不需要利用正交矩阵,构造结果更灵活、适用范围更广,能够生成多种不同形式的零相关区序列集。

A new construction method for zero correlation zone （ZCZ） sequence set is proposed based on the interleaving technique and perfect sequence. The perfect ZCZ sequence pair is generated by casca- ding and interleaving. Then, a new ZCZ sequence pair set is constructed by using the perfect sequence pair and the ZCZ sequence pair set based on the interleaving technique. During the constructing process, the duration of period and the ZCZ of resultant sequence pair set can be extended by replacing the orthogonal matrix with a ZCZ sequence pair set. Without the orthogonal matrix, the resultant construction is more flexible and applicable, thus it can generate various ZCZ sequence sets with different forms.
