On the 4-Adic Complexity of Quaternary Sequences of Period $2p$ with Ideal Autocorrelation
Minghui Yang, Shiyuan Qiang, Keqin Feng, Dongdai Lin · 2021
In this paper, we study the 4-adic complexity of two classes of quaternary sequences of period$2p$with ideal autocorrelation defined by Kim et al. (ISIT, 2009). Our results show that the 4-adic complexity of these two kinds of quaternary sequences is large enough to resist the attack of the rational approximation algorithm.
