中文摘要：

为了拓宽准同步码分多址系统中零相关区（ZCZ）序列的设计范围，将几乎最佳屏蔽序列偶应用于ZCZ信号设计中，提出了一种新的ZCZ屏蔽序列偶集的构造方法，并给出了利用周期乘积构造法从一个酉矩阵和一个ZCZ屏蔽序列偶集构造出新的ZCZ屏蔽序列偶集的方法．几乎最佳屏蔽序列偶和酉矩阵都很容易得到，因而使用所提方法构造出的ZCZ屏蔽序列偶集具有较大的容量，可更好地满足实际工程的需要．

英文摘要：

In order to extend the scope of zero correlation zone （ZCZ） sequence in quasi-synchronous code division multiple access system, an almost perfect punctured binary sequence pairs is used in zero correlation zone （ZCZ） sequence pairs, a new construction method for ZCZ signals is presented. ZCZ punctured sequence pairs set can be generated from the periodic product of unitary matrix and the original ZCZ punctured sequence pairs set. The almost perfect punctured binary sequence pairs and the unitary matrix can be easily obtained, so the capacity of ZCZ punctured sequence pairs set constructed by the proposed method is so large that they can satisfy requirements of engineering applications.
