摘要
混沌由于其自身的伪随机特性和初值敏感性,越来越受到人们的重视。就混沌的定义、特性、同步方式及其在通信中的应用作了介绍,指出当前将混沌应用于实际通信系统存在的一些问题,对未来混沌通信研究的发展方向进行了展望。并特别对混沌在超宽带无线通信和数字水印做了介绍。
With the property of pseudo-randomness and sensitivity to initial value, chaos has attracted great concern in the world. In this paper, the characteristics, definition, synchronous mode of chaotic system and the applications of chaos in secure communication systems are introduced. The problems of chaotic communication mechanism in practical applications and the way of future development are pointed out. In particular, the application of chaos in ultra-wide wireless communication and in digital watermark are recommended.
