摘要
特征向量法功率谱估计是基于矩阵分解的一种功率谱估计的非参数方法。通过分析数据加窗对自相关函数的影响对其提出改进,通过仿真试验证明,此算法的分辨率和抗噪性能得到很大改善。
Eigenveetor power spectrum estimation is based on matrix eigen decomposition. This paper analyzes the impaction correlation function by the weighted data with window and improves the EV estimation. Through the simulation, the result shows that the resolution is improved largely.
