A pair of binary sequences is generalized from the concept of atwo-level autocorrelation function of single binary sequence. Inthis paper, we describe two classes of binary sequence pairs ofperiod $N=2q$, where $q=4f+1$ is an odd prime and $f$ is an even integer.Those classes of binary sequence pairs are based on cyclic almost difference set pairs. Theyhave optimal three-level cross-correlation, and either balanced oralmost balanced.
