A new construction technique of ZCZ sequence pairs set
Junping Gao, Qi Li, Jufeng Dai · 2007
A new construction method for ZCZ sequence pairs set is presented. Based on perfect autocorrelation sequence pair and orthogonal matrix, ZCZ sequence pairs set with certain family size and zero correlation zone can be constructed through interleaved technique. The proposed technique unified the construction methods of ternary, quadriphase or polyphase ZCZ sequence pairs sets. And since ZCZ sequence can be considered as the special case of ZCZ sequence pahs, it also fits to create ZCZ sequences set. This will extend the existence scope of spreading sequences in QS-CDMA system.
