一种基于多卷保守混沌系统的伪随机信号发生器的设计及实现
Design and Implementation of a Pseudo-Random Signal Generator Based on Multi-Scroll Conservative Chaotic System
摘要
Abstract
In order to generate a new digital chaotic pseudo-random sequence,a multi-scroll conservative chaotic system with both Hamiltonian energy conservation and volume conservation is proposed in our present study.Dynamic characteris-tics of the system including conservative characteristics,stability,and multi-scroll characteristics were also respectively stud-ied based on theoretical analysis and numerical analysis.It is found that the system has good ergodicity,complexity and strong pseudo-randomness.National Institute of Standards and Technology(NIST)test was further performed for the system,and all the results met standard conditions for pseudo-random signals.Moreover,the multi-scroll conservative chaotic system was designed to implement by field programmable gate array(FPGA)technology,which has provided a multi-scroll conser-vative chaotic system model and a pseudo-random signal generator for chaos applications.关键词
