现代无线传输系统主要基于线性理论以保证合作方通信的有效性和可靠性，并未充分利用通信系统内在的非线性特征，无法系统地对非合作方截获信号的能力进行控制，且难以定量评估传输信号被截获的难易程度，需要发展一种可控的传输方法来解决该问题。因此，本项目拟引入非线性动力学研究信号域可控的无线传输方法：1）针对可控传输缺乏系统性理论指导的难题，利用动力学研究合作方与非合作方耦合形成的复杂系统，借鉴香农信道容量概念，给出截获信道容量的理论分析方法；2）针对难以定量评估传输信号被截获难易程度的难题，建立截获阈值和截获复杂度等定量指标评估无线传输可控性；3）以截获信道容量、截获阈值和截获复杂度为度量，从频谱、波形和编码三个环节引入非线性动力学，提出一种可控无线传输的方法。本项目的研究成果可在无线传输有效可靠的基础上，拓展可控性，将为可控无线传输提供理论框架、技术方案和评估方法，为当前常规设计方法提供有益的补充。

Modern wireless transmission systems are based on linear theory to ensure the effectiveness and reliability of cooperative communication.These systems not fully use the nonlinear characteristics existed in communication systems. They are unable to systematically control the ability of non-partners to intercept signals, and are difficult to quantitatively assess the ease with which the transmitted signal is intercepted. A controllable transmission method should be developed to solve these problems. Thus, this project intends to introduce nonlinear dynamics to study the controllable wireless transmission in signal domain. 1) For the problem of the lack of systematic and theoretical guidance for controllable transmission, complex systems coupled by partners and non-partners are researched using nonlinear dynamics. Meanwhile, drawing on the concept of Shannon channel capacity, this project also gives the theoretical analysis method for intercept channel capacity. 2) Quantitative indicators such as intercept threshold and intercept complexity for wireless transmission are established to assess the ease with which the transmitted signal is intercepted. 3) Based on intercept channel capacity, intercept threshold and intercept complexity, introducing nonlinear dynamics from three parts: spectrum, waveform and coding, a method for controllable wireless transmission is proposed. The results of this project can expand the controllability of wireless transmission based on the effectiveness and the reliability, provide a theoretical framework, technical solutions and evaluation methods for controllable wireless transmission, as well as a useful supplement to the current conventional design methods.
