| 摘 要： | 介绍多相正交序列的构造方法,对多相正交序列的自相关和互相关特性进行分析。提出采用多相正交序 列的移位序列作为扩频序列的通信方式,并给出接收端序列同步的实现方法。这种方式能解决低相数多相正交序列互 相关特性不理想,而高相数多相正交序列难以搜索的困难。

| Abstract: | The construction of multiphase orthogonal sequences is introduced and the capability of selfcorrelation and cross-correlation of multiphase orthogonal sequences is analysed.The communication mode of using shift-sequences of multiphase orthogonal sequences is brought up and the method for synchronization of sequence in receiver is presented.This method solves the problems that the capability of cross-correlation of multiphase orthogonal sequences is not good and the high phase multiphase orthogonal sequences can not be found easily.. |
