摘　　要：针对CDMA系统对地址码的要求,根据FH序列的性质和Naoki Suehiro提出的多相正交序列构造理论,系统地给出了一种多相正交序列的构造方法,对序列的性质进行了较深入的研究,并预测出此类序列的相关特性以及序列的个数,都能较好地满足扩频码的要求。In this paper, a kind of polyphase orthogonal sequence's structure method and its properties are stu died. The study is based on the FH sequence' s properties and the theory of structure of polyphase orthogonal sequence proposed by Naoki Suehiro according to CDMA system's require for the address sequence. And it is predicted that the correlation property of this kind of sequence and its number can satisfy the need of spread sequence to some extend.
