摘要

本文提出了一种基于忆阻开关模型的新型简单超宽带混沌发生器的先进设计系统(ADS)。提出了产生超宽带混沌信号的最简单的电子电路，并用倍周期图解、李雅普诺夫指数计算、混沌吸引子和分岔图等测试用例证明了混沌行为。本文给出了基于忆阻器的超宽带混沌发生器的ADS实现，并将实现结果与Matlab仿真结果进行了比较。同一混沌系统在较高的频率下工作，能够产生不同的序列，具有良好的相关特性和超宽带频谱。这些特性使我们的发生器非常适合基于超短持续时间脉冲的超宽带通信，这种通信产生的超宽带信号具有极低的功率谱密度。

ADS implementation of a new memristor based UWB chaotic generator

The paper present an ADS (Advanced Design System) implementation of a new and simple UWB (Ultra Wide Band) chaotic generator based on memristor switching model. The simplest electronic circuit to generate UWB chaotic signals is proposed, and chaotic behavior is proved using several test cases such as period-doubling illustration, lyapunov exponent's computation, chaotic attractors and bifurcation diagrams plots. This paper provides the ADS implementation of this memristor based UWB chaotic generator and compares implementation results with Matlab simulations. The same chaotic system working at higher frequency is capable of generating different sequences with good correlation properties and ultra wide band spectrum. These properties make our generator well suited for UWB communications based on ultra-short duration pulses which yield ultra-wide bandwidth signals characterized by extremely low power spectral densities.
