Abstract

In this paper, a new quaternary sequences over Z pq of length pq is constructed by using inverse Gray mapping and generalized cyclotomic sequences over Z p and Z q . The maximum nontrivial autocorrelation of the constructed sequences are shown to be p − q + 3 or \(\max\{q-p-1, \sqrt{5}\}\).
