摘要

研究了高斯相关干扰下非高斯过程谱估计的高阶谱分析问题。所得的高阶参数谱估计表达式用于非高斯过程的谱估计,这些谱估计可以用一般的自回归模型来描述。将接收到的参数谱三阶估计与基于傅里叶变换的已知方法计算的相似估计进行了比较分析。

The non-Gaussian signals' spectra estimation against a background of Gaussian correlated interference
The higher orders spectra analysis for non-Gaussian process spectrum estimation in the mix with Gaussian correlated interference are studied in the paper. The received expressions for parametric spectral estimation of higher orders are used for non-Gaussian processes spectra estimation that can be described by generic autoregressive models. The comparative analysis of the received parametric spectral third order estimations with similar estimations calculated using known methods based on Fourier transform was made.
