摘　　要：介绍了混沌数字通信系统研究的新进展。首先回顾了混沌数字通信的发展及其特点,对混沌键控调制方法的改进及其噪声性能进行了简要分析和综述。其次,着重分析了正交混沌移位键控(QCSK)调制和混沌脉位调制(CPPM)的原理及性能。最后总结和讨论了未来混沌数字通信研究的几个关键技术和方向。The recent development of chaos-based communication systems is described.We first review the development and characteristics of digital communications with chaos,in which the changes and the noise performance on chaos-shift-keying schemes are discused and surveyed briefly.Then,the principle and the performance of QCSK and CPPM are analyzed in detail.Finally,we conclude with a brief discussion on a few key techniques and challenges of employing chaos-based digital communication systems in the future.
