摘　　要：扩频序列设计和选择是码分多址(CDMA)数字蜂窝移动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特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序列及Walsh序列。文中从理论上和工程实用角度对扩频序列(m序列、Gold序列及Walsh序列等)的性能和特点进行了分析,同时给出了m序列、Gold序列及Walsh序列等的形成方法。Design and selection of spread spectrum code sequence is one of the key technologies of CDMA digital honeycomb mobile 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 and Walsh sequence are studied deeply and more used. This paper analyzed the perfromances and characters of spread spectrum sequences in theory and engineering practice,at the same time gave the forming methods of m sequence,Gold sequence and Walsh sequence and so on.
