| 摘 要： | 提出一种基于调制器的参数控制噪声干扰下的混沌数字通信方法，通过利用一种混沌系统驱动另一种混沌系统产生出理想的输出波形，将这种控制方法用于混沌数字通信控制，根据噪声干扰下的系统方程构造出状态调制器，并将其用于具有量测噪声和输入噪声干扰下的Lorenz混沌系统的控制．改变调制器的作用范围，可以将混沌系统稳定到一定的区域内．仿真结果证实了该方法的有效性．

| Abstract: | This paper puts forward a parameter-controlling of chaotic digital communication with noise interference based on modulator. An ideal output wave shape is produced by driving one chaos system to another. The control way can be used for chaos control according to the system equation under noise interference. State modulator is structured and it is used in Lorenz chaos system control which is under the interference of quantitative measure noise and input noise. Chaos system can be set to intrinsic block by changing acting frame work of modulator. The validity of this method is confirmed by an imitation of read result. |
