| 摘 要： | 在扩频通信中，扩频码的选择和构造是关键技术之一．扩频码良好的相关特性和随机性对码分多址通信系统的性能具有决定性的作用，系统的抗干扰、抗多径衰落、抗截获、保密、多址能力、同步实现等均与所采用的扩频序列密切相关．只有通过现有扩频码的充分分析和研究才有可能寻找到新的、性能更佳的扩频序列或它们的合理组合．

| Abstract: | Design and selection of spread spectrum code sequence is one of the key technologies of CDMA spread spectrum communication. 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. |
