摘　　要：基于完备序列和正交序列集,研究了零相关区序列集的构造方法。借助有限域上构造方法的思想,实现了最佳零相关区序列集的构造,且通过改变集合O和集合R,生成多个移位不等价零相关区序列集,扩展了序列集的数量。所提构造方法在满足p=Z/N或p^n=Z/N的条件下,其中p为素数,零相关区长度可以灵活选择,以满足不同系统对信道时延的要求。The construction of zero correlation zone(ZCZ)sequence set was researched based on perfect sequences and orthogonal sequence set.With the method of constructing on finite field,the optimal zero correlation zone sequence sets were constructed,by changing the setO and R,multiple shift distinct ZCZ sequence sets could be obtained and the number of sets could be expended.Through the constructions,the length of ZCZ can be chosen flexibly to meet the requirements of different systems for channel delay under the condition of p=Z/N or p^n=Z/N,where p is a prime.
