Abstract
In the QS-CDMA systerm,using the ZCZ sequence pairs can avoid the co-channel interference and multi-access interference. In this paper,a new construction method for ZCZ sequence pairs set is presented. Based on perfect binary sequence pair,ZCZ sequence pairs set with certain family size and zero correlation zone can be constructed through interleaved technique. The proposed technigue can construct ZCZ sequence pairs sets with different family size and different zero correlation zone through choosing different zero correlation zone freely in a certain range.
