Abstract
An asymmetric zero-correlation zone (A-ZCZ) sequence pairs set is a zero-correlation zone (ZCZ) pairs set consisting of multiple ZCZ sequence pairs subsets, where two arbitrary sequence pairs which belong to different subsets should have a large zero cross-correlation zone (ZCCZ). Additionally, each subset is a typical ZCZ sequence pairs set. The new proposed A-ZCZ sequence pairs sets can be generated based on interleaved technique and perfect sequence pairs of length \(P= Nmk\) with \(N>1\), \(m\ge 1\), \(k>1\). The proposed A-ZCZ sequence pairs sets are applied to quasi-synchronous code-division multiple-access (QS-CDMA) systems and it can hypothetically achieve larger ZCCZ than typical ZCZ sequence pairs set, as well as eliminating both multiple access and multipath interference in the QS-CDMA system.
