Ensembles of periodic binary sequences with low off-peak autocorrelation and cross-correlation are highly valued and difficult to find. The small Kasami, Kamaletdinov 1&2, and Rational Cycle are versatile, because they can be converted into Costas-li

An algebraic method for designing unimodular sequence with two-level periodic autocorrelations by solving a trigonometric equation is proposed. Based on this algebraic method, new constructions of p-ary (p = 3,5) sequences arc presented.
