摘要
首先说明确定的非线性方程可以发展成为混沌的过程 ,继而由信号的统计特性和时频特性证明了Logist序列是平稳的随机过程。通过比较Logist混沌序列和白噪声的统计特性和时频特性 ,说明当 μ =4时的Logist方程可以产生白噪声 ,并以Labview为平台 ,设计了一台简易的虚拟白噪声发生器。
The nonlinear Logist equation can develop to chaotic process. That Logist iterated sequence is smooth random process is proven by statistical characteristic and time-frequency characteristic. The issue that Logist equation may generate white noise when parameter μ equal 4 is presented by comparing the statistical characteristic and time-frequency characteristic of Logist chaotic sequence and white noise. A virtual white noise generator's realization is given based on Labview.
