摘　　要：该文给出了一种构造三元多子集零相关区(ZCZ)序列集的方法。这类新的ZCZ序列集含有多个子集,每个子集构成一个ZCZ序列集,不同子集间存在零相关区。构造法基于二元Hadamard矩阵,通过添零的方法得到了一类三元的多子集ZCZ序列集,同Hayashi结果相比具有相同的性能参数但是具有更多序列数目。A construction of multiple Zero Correlation Zone （ZCZ） sequence sets is presented. The new ZCZ sequence set consists of several subsets, each subset is a ZCZ sequence set by itself and the cross-correlation function between sequences belonging to different subsets also has a zero-correlation zone. The sequence sets constructed are multiple ternary ZCZ sequence sets, these sequence sets have the same performance parameters but larger set size compared with that constructed by Hayashi.
