New Families of Binary Sequence Pairs With Two-Level and Three-Level Correlation
Xiuping Peng, XU Cheng-qian, K. T. Arasu · IEEE Transactions on Information Theory · 2012
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 N = np, where gcd(n,p) = 1, and optimal correlation values -1 are constructed, as well as new families of binary sequence pairs with three-level correlation and period N≡0(mod 4). For the new binary sequence pairs with optimal correlation values, their corresponding new difference set pairs and almost difference set pairs are also derived.
