Abstract
In this paper, the quasi-orthogonal sequences (QOS) designed from jacket matrices are introduced. In contrast to the conventional QOS design on Walsh sequences, we now investigate polyphase sequences on jacket matrices. The proposed quasi-orthogonal sequences could enlarge the number of users and retain the lower cross-correlation property. Additionally, a simple recursive method to find the proper bent sequences is presented. The new method can easily give extended QOS constructions.
