Zero Correlation Distribution of ZCZ Sequences Obtained from a Perfect Sequence and a Unitary Matrix

摘要

A class of zero-correlation zone (ZCZ) sequences constructed by the recursive procedure from a perfect sequence and a unitary matrix was proposed by Torii,Nakamura, and Suehiro [1]. In the reference [1], properties of just enough for the class of sequences used in approximately synchronized CDMA (AS-CDMA) systems were considered. In this paper, we give more detailed distributions of correlation values for their ZCZ sequence sets, and expect that the results make an effect on any applications employing AS-CDMA systems.
