摘　　要：组间零相关区周期互补序列集适用于多小区环境下的多载波准同步扩频通信系统的地址码,但这类地址码数量不够丰富,为此本文基于零相关区序列集和整数集,构造了一类组内零相关区与组间零相关区相等的周期组间零相关区互补序列集。该方法得到的序列集中,用户数、零相关区长度以及集合的组数都可以灵活选择。由于零相关区序列集和整数集存在的数目很多,因此通过本方法可以构造出大量的组间零相关区周期互补序列集。Inter-group zero correlation zone complementary(IGZC)sequence sets are suitable for community environment multicarrier quasi-synchronization spread spectrum communication system,but those are not rich.In this paper,based on the zero correlation zone sequence and integer sets,a class of IGZC sequence sets are constructed,in which intragroup zero correlation zone(ZCZ)is equal to intergroup ZCZ.The number of users,the length of the zero correlation zone and the number of groups can be selected flexibly.Due to the large number of ZCZ sequence sets and integer sets,a numerous IGZC sequence sets can be constructed by this method.

关 键 词：组间零相关区互补序列集 零相关区 整数集
