A novel zero correlation zone sequence pairs set

Jinming Liu

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.
