摘　　要：介绍现代功率谱估计中AR模型参数的几种典型求解算法,并比较其性能指标,采用功能强大的MAT-LAB软件对各种算法的功率谱估计进行仿真,从实验的角度讨论了这几种功率谱估计法的优缺点,以便在实际工作中做出合理的选择。The typical algorithms of PSD Estimation based on AR model are presented, and their performances are analyzed in this paper. These methods for AR model parameter algorithm are implemented by very simple m-files on MATLAB. Moreover, the advantages and disadvantages of these methods are discussed from the point of view in experiment for proper applications.
