摘要
提出了一种新的混沌序列Tent映射,分析了映射的数字混沌序列的产生方法.通过对该数字混沌序列的直接序列扩频通信系统的分析,以及Simulink仿真实验,表明新的数字混沌序列有更好的传输特性,满足扩频通信系统的性能要求.
A new chaotic sequence based on Tent-map is proposed in this paper. The method of generating the Tent-map digital chaotic sequences is analyzed. Through analyzing the digital chaotic sequence applied in direct sequence spread spectrum communication system and Simulink simulation,the results show that the new digital chaotic sequence,which meets sperformance requirements of spread spectrum communication system,has better transmission characteristics.
