摘要 本文提出了一种稳定分布白噪声的概念及其判断标准,对传统意义上的白噪声进行了广义化,提出了一种非线性系统中稳定有色的噪声概念并建立其非线性PAR模型,提出EIRLP算法对多项式自回归稳定有色噪声的模型参数进行估计,并探讨了其白化方法.计算机模拟表明,这种算法是一种在高斯和分数低阶稳定分布噪声条件下具有良好韧性的白化滤波方法. This paper briefly proposes a new different spectral density from power speetnun density of the second order processes, thus we can get a new concept of stable white noise based on covariafion spectrum, and a method of whitening in nonlinear system under alpha-stable conditions. Simulation and analysis show that the method is robust and generalizes the conventional whitening filters based on second order statistics.
