| 摘 要： | 在准同步CDMA系统中,使用零相关区(ZCZ)序列能避免共信道冲突和多址干扰。应用序列偶理论,定义了1种新型的扩频序列集———ZCZ序列偶集合,提出了1种构造ZCZ序列偶集合的迭代法,该方法构造的ZCZ序列偶集合具有较长的零相关区,可用作准同步CDMA系统的扩频序列。

| Abstract: | In quasi-synchronous CDMA systems,using the ZCZ sequences can avoid the co-channel interference and the multi-access interference.Applying the theory of sequence pairs,this paper defines a new spread spectrum sequence set,or a ZCZ sequence pairs set.In addition,an iterative method for constructing ZCZ sequence pairs set is presented,the method can generate sets of ZCZ sequences having a longer zero-correlation zone,suitable for quasi-synchronous CDMA systems. |
