摘　　要：地址码在CDMA通信系统中占有重要地位,它决定着系统的容量、抗干扰性等重要指标。本文在NaokiSuehiro提出的多相序列构造理论的基础上,对其相关性进行分析、研究,并与当前性能较佳的二元序列进行对比。结果表明,多相序列具有优异的性能,适合用作CDMA系统中的地址码。Address code is very important in CDMA communication systems. It decides the capacity and the capability of anti-jamming of this system. This paper analyzes the correlation of multiphase sequences that proposed by Naoki Suehiro. Then we compare the correlation of multiphase sequence with the correlationof of binary sequences. The result shows that multiphase sequence has better performance and fits for CDMA communication systems.
