摘要：

为降低甚至消除准同步码分多址(CDMA: Code Division Multiple Access)系统的多径干扰和多址干扰, 满足系统不断增大的用户容量需要, 给出一种新的ZCZ(Zero Correlation Zone)序列偶集的构造方法。该方法基于三元最佳序列偶和正交矩阵偶（二元或三元）, 构造初始的ZCZ序列偶集, 这类序列偶集的性能参数可达到理论界。通过对序列偶移位, 再与移位不等价向量相乘, 以扩展已经构造的序列偶集。研究结果表明, 该类ZCZ序列偶集序列偶的数量与零相关区长度及设定的参数有关, 通过设置参数值, 即可得到不同的ZCZ序列偶集。

Abstract:

A new construction of ZCZ(Zero Correlation Zone)sequence pairs set is presented. It can be used in AS CDMA (Approximately Synchronized Code Division Multiply Access) system for the reduction or elimination of the multipath interference and multiple access inter access interference of the system. Based on ternary perfect sequence pairs and orthogonal matrix pairs (binary or ternary), the initial ZCZ sequence pairs set, the performance parameter of which could achieve Theory Circle, is constructed. Then extend the constructed ZCZ sequence pairs set by multiplying with unequal vectors after shifting, we get a class ZCZ sequence pairs set. The number of sequence pairs and the length of zero are related to parameters, different ZCZ sequence pairs sets can be obtained by setting parameters.

Key words: approximately synchronized code division multiply access （AS CDMA）, perfect sequence pairs, orthogonal matrix pairs, zero correlation zone （ZCZ）sequence pairs set
