Multiple access communication based on control of special chaotic trajectories

The necessity of simultaneous access to one communication channel by many users, has led to the development of the corresponding standards: FDMA, TDMA and CDMA. In multiple-access systems, chaotic signals are used only as efficient and versatile means of quasi-noise signal formation. In such applications, important and attractive features, such as multitude of chaotic modes, flexible control of their dynamics, chaotic self-synchronization phenomena, and potential communication confidence due to the very dynamic properties of chaotic nonlinear systems, are neglected. Here we discuss another principle of multiple access, based on the fine structure of chaotic attractor, using control of special chaotic trajectories. We also demonstrate the experimental verification of the proposed approach for asynchronous packet data transmission.
