| 摘 要： | 在准同步CDMA系统中,使用零相关区域(ZCZ)序列能够避免共信道冲突和多址干扰。应用序列偶理论,定义一种新形式的扩频序列集———ZCZ序列偶集合,并介绍一种构造ZCZ序列偶集合的迭代方法。

| Abstract: | In quasi-synchronous CDMA systems,the use of Zero-Correlation Zone(ZCZ) sequences can avoid co-channel interference and multi-access interference.Applying the theory of sequence pairs,a new spreading sequence set is defined in this paper which is a ZCZ sequence pairs set.In addition,an iterative algorithm for constructing the ZCZ sequence pairs set is presented. |
