In this paper, A construction of shift sequence sets is presented, based on these shift sequence sets one can get many cyclically distinct zero-correlation zone (ZCZ) or low-correlation zone (LCZ) sequence sets by utilizing interleaving technique. Compared with previous constructions, the present method can provide more spread-spectrurn sequences for quasi-synchronous CDMA (QS-CDMA) systems. More than that, mutually orthogonal sets of zero-correlation zone sequences are also constructed based on these shift sequence sets.%本文给出了移位不等价序列集的概念,提出一种移位序列构造方法,并基于这种移位序列,利用交织法得到了多个移位不等价的低零相关区序列集.同以前方法相比扩展了序列集的数量,可以为准同步CDMA通信系统提供更多的扩频序列.通过本文方法还可以利用任意长度的完备序列来构造相互正交的零相关区序列集,放宽了对完备序列长度的限制,从而可以得到更多的相互正交的零相关区序列集.
