Abstract

Su et al. proposed several new classes of quaternary sequences of even length with optimal autocorrelation interleaved by twin-prime sequences pairs, GMW sequences pairs or binary cyclotomic sequences of order four in \cite{S1}. In this paper, we determine the 4-adic complexity of these quaternary sequences with period 2n2n by using correlation function and the "Gauss periods" of order four and "quadratic Gauss sums" on finite field Fn\mathbb{F}_n and valued in Z42n1\mathbb{Z}^{*}_{4^{2n}-1}. Our results show that they are safe enough to resist the attack of the rational approximation algorithm.
