摘　　要：提出一种新的具有良好周期相关特性的准最佳离散信号——ZCZ阵列偶,并给出其构造方法。基于最佳阵列偶和正交矩阵,通过选择适当的移位序列,经行、列交织可以生成具有一定体积、阵列信号数目和零相关区的二维ZCZ阵列偶集合。除二元情况外,此方法还可应用到多元ZCZ阵列偶集合的生成。所得ZCZ阵列偶扩展了二维最佳离散信号的选择空间,并可作为多用户信号应用到实际工程中。A new quasi-perfect discrete signal--ZCZ array pair which has good periodic correlation property and its construcfion method was proposed. Based on perfect array pair and orthogonal matrix, ZCZ array pairs set with certain volume, family size and zero correlation zone can be synthesized through row or column interleaved technique when suitable shift sequences are selected. Except the binary case, the proposed technique can be applied to synthesize polyphase ZCZ array pairs set also. These ZCZ array pairs sets are feasible as multi-user signal, and extend the selectable scope of two-dimension perfect discrete signal.
