| 摘 要： | 扩频序列设计和选择是码分多址（CDMA）扩频通信的关键技术之一，扩频码序列的设计就是构造不同结构的具有良好相关性的伪随机序列来满足CDMA系统的要求。目前研究最深入的和使用最多的是m序列和Gold序列，另外国内一些学者还提出了真正正交的序列。文中对扩频序列的相关性和特点进行了分析，并给出了各序列的生成方法。

| Abstract: | Design and selection of spread spectrum code sequence is one of the key technologies of CDMA spread spectrum communication. The design of spread spectrum code sequence is constructing pseudo - random sequence which is possessed of different structure and good performances in order to satisfy the need of CDMA system. At present the m sequence, gold sequence are studied deeply and more used. Some scholars have put forward certain really orthogonal code. This paper analyzed the performances and characters of spread spectrum sequences ,at the same time gave the forming methods of various sequence codes. |
