| 摘 要： | 用交织方法研究ZCZ序列集合的构造，提出了基于交织技术的ZCZ序列构造的新方法．对于给定的周期为L的最佳自相关序列a和正交矩阵峨，首先选择合适的移位序列，对序列a进行交织得到（L，N）-交织序列b；再用正交矩阵HN将交织序列b扩展为新的序列集，则该序列集就是所构造的ZCZ序列集．用该方法可以构造达到或接近理论界的具有大的零相关区的ZCZ序列集，并统一了三元、四相和多相ZCZ序列集构造方法。

| Abstract: | Interleaved technique was used to construct a zero correlation zone(ZCZ),and a new method was proposed to design sequences with ZCZ.For a given perfect sequence a of a period L and an orthogonal matrix,a new sequence b is generated by interleaving the sequence a first,then a new ZCZ sequence set is obtained by extending b with the orthogonal matrix.The ZCZ sequence set constructed with the proposed method can reach or approach the mathematical bound, and the methods for construction of ternary,quadripahse or polyphase ZCZ sequences are unified with the proposed method. |
