Construction Methods of ZCZ Punctured Sequence Pairs Set
Yaping Chi · Beijing Youdian Xueyuan xuebao · 2011
In order to extend the scope of zero correlation zone(ZCZ) sequence in quasi-synchronous code division multiple access system,an almost perfect punctured binary sequence pairs is used in zero correlation zone(ZCZ) sequence pairs,a new construction method for ZCZ signals is presented.ZCZ punctured sequence pairs set can be generated from the periodic product of unitary matrix and the original ZCZ punctured sequence pairs set.The almost perfect punctured binary sequence pairs and the unitary matrix can be easily obtained,so the capacity of ZCZ punctured sequence pairs set constructed by the proposed method is so large that they can satisfy requirements of engineering applications.
