In this paper, for a prime p and a positive integer q such that q|pn − 1, we constructed q-ary Lempel– Cohn–Eastman(LCE) sequences with period p − 1. These sequences have maximum autocorrelation magnitude bounded by 4. Particularly, in the case of q = 3, the maximum autocorrelation magnitude of the ternary LCE sequences is 3. And the maximum autocorrelation magnitude of the quaternary LCE seque...
