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