A multichannel digital communication method using the synchronization of globally coupled chaotic systems is proposed. The proposed method allows several binary messages to be transmitted simultaneously by just one transmitted chaotic signal, provided that outputs of different units are uncorrelated. We demonstrate the communication method on a model system consisting of Lorenz-like units. We also show how to systematically construct high-dimensional synchronizing units, based on the idea of cascaded systems. Furthermore, the dynamics of the coupled chaotic systems is discussed with particular attention paid to the correlation between the motions of different units.
提出了一种利用全局耦合混沌系统同步的多通道数字通信方法。该方法允许仅通过一个传输的混沌信号同时传输多个二进制消息,前提是不同单元的输出不相关。我们在一个由类洛伦兹单元组成的模型系统上演示了这种通信方法。我们还展示了如何基于级联系统的思想系统地构建高维同步单元。此外,还讨论了耦合混沌系统的动力学,特别关注不同单元运动之间的相关性。
