摘　　要：该文基于2元序列支撑集和低相关序列集,提出一种新的周期准互补序列集构造框架。在此框架基础上,分别利用最优4元序列族A、族D和Luke序列集提出了3类渐近最优和渐近几乎最优周期准互补序列集,序列集参数由2元序列和低相关序列集共同决定。与传统的完备互补序列集相比,所构造的准互补序列集具有更多的序列数目,应用到多载波扩频通信系统中可以支持更多的用户。Based on the support of binary sequences and low correlation sequence sets,a new framework for constructing periodic quasi-complementary sequence sets is proposed.Based on this framework,three classes of asymptotically optimal and asymptotically almost optimal periodic quasi-complementary sequence sets are proposed by using the optimal quaternary sequence family A,family D and Luke sequence set,respectively.In addition,the parameters of sequence set are determined by the binary sequence and the low correlation sequence set.Compared with the traditional complete complementary sequence set,the quasi-complementary sequence set includes more sequences,which can support more users in multi-carrier spread spectrum communication system.

关 键 词：准互补序列集 2元序列 低相关 渐近最优
