Abstract

Let \(p, q\) \((p<q)\) be two odd primes with \(gcd(p-1,q-1)=6\). In this paper, based on the Whiteman generalized cyclotomy, new generalized cyclotomic sequences with order six and length \(pq\) are constructed. We first calculate the autocorrelation values of these sequences and get conditions of \(p\) and \(q\) such that they are four-valued. Besides, we find some specific examples such that the autocorrelation function takes on only a few values.
