Abstract :
Sequences with optimal autocorrelation property are needed in certain communication systems and cryptography. In this paper, a construction of balanced quaternary sequences with period N ≡ 2 (mod 4) and optimal autocorrelation value and a construction of almost balanced binary sequences with period N ≡ 0 (mod 4) and optimal autocorrelation value are presented. Both constructions are a generalization of earlier ones.
