摘　　要：2000年,Tang,Fan和Matsufuji给出(L,M,Zcz)-ZCZ序列簇的理论界为Zcz≤L/M-1。给定正整数n和L,本文给出一个交织ZCZ序列簇的构造算法,该算法由L条周期为L的正交序列簇生成一类(2n+1L,2L,2n-1)-ZCZ序列簇。若n≥2且4|τ,该类ZCZ序列簇中编号为奇数的序列与编号为偶数的序列在移位为τ时相关值为零。此外,选择不同的正交序列簇或不同的移位序列,经构造算法可以生成不同的ZCZ序列簇。In 2000, Tang, Fan and Matsufuji presented the theoretical bound of an （L,M, Zcz） -ZCZ sequence family is Zcz ≤L/M-1. In this paper, for given positive integers n and L, a construction algorithm of interleaved ZCZ sequence families is proposed, by which a class of binary （2^n＋1L,2L,2^n-1） -ZCZ sequence families can be generated from an orthogonal sequence family composed of L sequences with period L. If n ≥ 2 and 4 ｜τ, the correlation value between even-number-indexed sequences and odd-number-indexed sequences with shift T of this sequence family is zero. Furthermore, choose different orthogonal sequence families or different shift sequences, different ZCZ sequence families can be generated by this construction algorithm.
