| 摘 要： | 扩频序列的选择涉及扩频通信的性能,对移动通信和个人便携通信的发展均将产生重要影响.文章利用Matlab对零均值L0gistic映射的混沌序列进行仿真,分析了该序列不同于其他扩频码的特点及优势,验证了将其作为扩频序列的可行性.在此基础上,对基于该序列的混沌通信系统--DCSK进行可视化仿真,讨论了其良好的扩频码特性和抗干扰特性,认为该系统为进一步研究混沌扩频通信搭建了一个良好的仿真平台.

| Abstract: | It will involve the performance of spread spectrum communication to choose the spread spectrum sequence, it will come into being an important influence on the development of mobile communication and personal portable communication. The author utilizes Matlab to carry through the simulation of Logistic mapping zero mean value chaos sequence, analyses this kind of sequence, its characteristic and advantage, which is different from others. The article has verified the feasibility to use this kind of spread spectrum sequence. On this basis, to the DCSK Chaos communication system which is based on this sequence, the visual emulation was carried through, its good spread spectrum characteristics and anti-interference characteristic were discussed, this DCSK will provide a good simulation platform for further studying the chaos spread spectrum communication. |
