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.
In order to broaden the design range of zero correlation region (ZCZ) sequence in quasi-synchronous CDMA system, almost the best shielding sequence is applied to ZCZ signal design. A new construction method of ZCZ shielding sequence even set is proposed. And gives a method to construct a new ZCZ mask sequence even set from a unitary matrix and a ZCZ mask sequence using the period product construction method. Almost optimal mask sequence even and unitary matrices are easily obtained, The ZCZ shielding sequence constructed by the method has a large capacity and can better meet the needs of the actual project.
