分别用Logistic映射和Chebyshev映射产生出混沌序列,在Matlab下进行相关性分析,再以Chebyshev映射产生的混沌序列代替传统的伪随机序列作为扩频通信系统的扩频码,在Simulink下进行扩频通信系统的仿真,综合分析了基于混沌序列的扩频系统的抗噪性能,仿真结果验证了基于混沌序列的扩频系统的抗干扰性能和混沌序列作为码的应用价值。
Respectively produced chaotic sequences by logistic map and chebyshev map,and made correlation analysis under the Matlab environment.Instead of tranditional PN codes,this paper used chaotic sequences produced by Chebyshev map as the Spread Spectrum(SS) code in SS communication system.Simulation of SS communication system under Simlink,shows the anti-jamming capacity of the chaotic sequences.
