In this letter, zero-correlation zone (ZCZ) aperiodic complementary sequence (ZACS) sets with low column sequence peak-to-mean envelope power ratio (PMEPR) are introduced. Based on Golay sequences with large zero autocorrelation zone and orthogonal matrix, a class of ZACS sets are constructed. When each sequence is arranged to be a matrix, the PMEPR of column sequence is at most 2.Index Terms-ZACS (ZCZ aperiodic complementary sequence), column sequence, PMEPR (peak-to-mean envelope power ratio).

A pair of binary sequences is generalized from the concept of a two-level autocorrelation function of a single binary sequence. In this paper, new families of binary sequence pairs with period , where gcd , and optimal correlation values are constructed, as well as new families of binary sequence pairs with three-level correlation and period . For the new binary sequence pairs with optimal correlation values, their corresponding new difference set pairs and almost difference set pairs are also derived.Index Terms-Almost difference set pair (ADSP), binary sequence pair, difference set pair (DSP), optimal correlation value.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
