New Family of Spreading Sequences for Quasi-Synchronous CDMA Systems

Abstract

Based on the generalized Chirp-like sequences, the product technique is extensively used to construct a new family of spreading sequences, and its correlation property is verified. The results show that among the proposed sequences, there are subclasses of sequences with a zero-correlation zone, which can be used in quasi-synchronous-code division multiple access systems.
