论文摘要
这项工作表明，具有不同功率谱的混沌信号对线性叠加是可靠的，这意味着叠加保留了千古量（Lyapunov指数）和源信号的信息含量，即使在非理想的物理培养基上传播后也是如此。混乱信号使我能够根据混乱提出一种新颖的通信系统，在该信息中，每个用户的信息都以不同的基本频率运行，并且在露天无线物理介质中可以完全保留，并且可以完全保存在露天无线物理培养基中，并且可以用较低的错误误差来解码。这项工作非常详细地解决了混乱的信号及其信息含量在介绍多径传播，噪声和混沌干扰（线性叠加）的非理想特性的介质时如何影响，以及这如何影响提议的通信系统。还讨论了具有其他非理想特性（分散和对周期信号的干扰）的物理媒体。
This work shows that chaotic signals with different power spectrum are robust to linear superposition, meaning that the superposition preserves Ergodic quantities (Lyapunov exponents) and the information content of the source signals, even after being transmitted over non-ideal physical medium. This wonderful property that chaotic signals have allows me to propose a novel communication system based on chaos, where information composed from and to multiple users each operating with different base frequencies and that is carried by chaotic wavesignals can be fully preserved after transmission in the open air wireless physical medium, and it can be trivially decoded with low probability of errors. This work tackles with great detail how chaotic signals and their information content are affected when travelling through medium that presents the non-ideal properties of multipath propagation, noise and chaotic interference (linear superposition), and how this impacts on the proposed communication system. Physical media with other non-ideal properties (dispersion and interference with periodic signals) are also discussed.
