基于混沌同步的混沌脉冲定位调制研究

随着混沌理论和混沌同步的发展及完善，根据混沌脉冲定位调制（CPPM）的基本原理，提出一种基于混沌同步的混沌脉冲定位调制（CS—CPPM）实现方法，建立以蔡氏混沌同步电路和Logstic映射为例的实现模型，用EWB仿真软件对蔡氏二极管、蔡氏电路以及蔡氏同步电路进行分析和实现，最后用Matlab对整个系统进行仿真，实验结果论证了该方法的可行性．这样使得混沌脉冲定位调制信号可以利用现有的混沌映射实现．从而具有多样性和稳定的混沌特性。也使得混沌脉冲定位调制（CPPM）技术具有更多的实现途径和更深的研究与应用价值。

Research on Chaotic-Pulse-Position Modulation Based on the Chaotic-Synchronization

With the development and perfectness of chaotic theory and chaotic-synchronization we present a new method to realize CS-CPPM in this paper, according to the rationale of CPPM. We make a realization model which is based on the Chua's chaotic-synchrontztion circuit and Logstic mapping. We use EWB to analyse and implement the Chua's diode, the Chua's circuit and the Chua's synchronization circuit. At last, we use Matlab to simulate the whole system. The experiment result demonstrates the feasibility of the way. The CS-CPPM can be realized from the present chaotic-mapping, multiplicity and stable chaos are its characters. It owns more realiztion ways and values to study and apply.
