摘要
为了更好地模拟计算功率谱,采用了现代功率谱估计中常用的基于AR模型的自相关法和Burg法,通过仿真给出了估计出的功率谱曲线,结果表明,Burg算法在谱分辨率方面有着良好的性能。选择合适的采样点数来确定模型阶数,给出阶数选择的原则。
A self-correlation method and Burg method based on AR model are usually used in the modern PSD for better simulating and computing the power spectrum. Through simulation, PSD curve is acquired by three methods. The results show that Burg method has good performance in the spectral resolution. An appropriate sampling point should be selected to determine the model order. At the same time, the principle of order selection is given.
