摘要
与以往扩频通信系统不同,本文用序列偶代替Gold码应用于扩频通信系统。随着CDMA通信系统的应用范围越来越广泛,目前可用的地址码的数量有限并且码长均有限,这样就给实际工程带来很大的不便。本文首先介绍了序列偶的概念和几种重要的盲多用户检测方法。再将满足一定条件的序列偶应用于盲多用户检测中,通过理论分析和实验仿真,证明了序列偶应用于扩频通信系统的可行性。因此序列偶能很好的弥补目前扩频码存在的数量有限的缺陷,作为现有扩频码的有效补充。
Different from early spread communication system, this text uses CDMA communication system widely used, and the number and length sequence pairs substitute Gold. Along with of address code are both limited, it is inconvenient to apply in practice. Sequence pairs and some of important blind multiuser detections are discussed. Then the sequence pairs which satisfy the certain given conditions are applied to blind MUD. Through theoretical analysis and experimental simulation, the feasibility of sequence pairs being applied to spread spectrum system is proved. So sequence pairs can remedy the number restriction of spread spectrum code and supply it well.
