Zero correlation zone (ZCZ) sequences have received much research attention in many practical applications, such as quasi‐synchronous code‐division multiple‐access systems and MIMO systems. In this study, three constructions of multiple polyphase ZCZ sequence sets with low inter‐set cross‐correlation property are proposed. The resultant periodic ZCZ sequence sets are optimal with respect to the theoretical bound and have new parameters uncovered in the literature. Consequently, a great deal of flexibility may be provided in the choice of periodic optimal ZCZ sequence sets with good inter‐set cross‐correlation property for their applications.
