In this paper, new families of zero correlation zone (ZCZ) sequences based on interleaving technique and perfect sequences are constructed. The proposed sequences have the property that, in a specified zone, the out-of-phase autocorrelation and cross-correlation values are all equal to zero. Due to this property, such sequences are suitable for quasi-synchronous code-division multiple access (QS-CDMA) systems. It is shown that that all the proposed ZCZ sequences are pairwise cyclically distinct. Furthermore, the condition under which the constructed ZCZ sequences are optimal is derived.
