双模噪声背景下参数化谱估计方法
摘要
本文采用高阶统计量的方法在双模噪声背景下对非高斯ARMA信号进行参数化谱估计
主要利用双模噪声概率密度的对称性
使用总体最小二乘算法实现对非高斯信号的模型建立
再对模型产生的信号进行双谱估计
通过仿真能得到比基于二阶统计量的参数化方法及非参数化方法都更好的谱估计效果.
Abstract
This paper makes parametric spectrum estimation of Non-Gaussian ARMA signal by high-order statistics with bimodal noise
sets up the model of Non-Gaussian signal using symmetry of bimodal noise probability density and total least squares algorithm to estimate bispectrum
it can get better estimation effect than that obtained by the parametric and non-parametric method based on the second order statistics through simulation.
