报告摘要：Quaternary sequences with optimal auto-correlation property are preferred in applications. Recently, several classes of optimal quaternary sequences of period $2p$, which are all closely related to the cyclotomic classes of order 4 with respect to $\mathbb{Z}_p$ were introduced in the literature. However, less attention has been paid to the equivalence between these known results. In this report, we introduce the unified form of this kind of quaternary sequence to classify these known results and then conclude the unified forms of these optimal quaternary sequences. By doing this, we disclose the relationship between the optimal quaternary sequences derived from different methods in the literature. This talk is based on a joint works with P. Qiao and Y. Yang.
