Quaternary sequences of both even and odd period having low autocorrelation are studied. We construct new families of balanced quaternary sequences of odd period and low autocorrelation using cyclotomic classes of order eight, as well as investigate the linear complexity of some known quaternary sequences of odd period. We discuss a construction given by Chung et al. in “New Quaternary Sequences with Even Period and Three-Valued Autocorrelation” (IEICE Trans. Fundam. Electron. Commun. Comput. Sci.E93-A(1), 309–315 2010) first by pointing out a slight modification and then by showing that, in certain cases, this slight modification generalizes the construction given by Shen et al. in “New Families of Balanced Quaternary Sequences of Even Period with Three-level Optimal Autocorrelation” (IEEE Commun. Lett.2017(10), 2146–2149 2017). We investigate the linear complexity of these sequences as well.
