【摘要】 扩频通信由于具有良好的保密性和抗干扰的能力,在现代通信系统中得到了广泛的应用。而以混沌为基础的调制技术在近年也得到了广泛的研究。文中在分析了扩频通信的基础上,引入了基于混沌的扩频通信系统的原理和方框图。对混沌系统和传统的数字通信系统进行了比较和仿真。更多还原

【Abstract】 Due to excellent ability of security and anti-jamming,spread-spectrum communication has a great deal of applications in modern communication system. The modulation technology based on chaos has been studied in recent years. On the basis of analyzing spread-spectrum, this paper introduces the principle and block diagram of spread-spectrum communication system based on chaos, and compare the performance of chaos system with traditional digital communication system.更多还原
