摘要
介绍了现代功率谱估计中的Burg算法最大熵谱估计的基本原理,并采用VC++语言对功率谱密度(PSD)进行了仿真。同时比较了Burg算法和经典谱估计中Bartlett周期图法,针对Burg算法中的模型阶次的选择进行了分析,提出了最佳模型阶次采用最终预报误差(FPE)为准则的结论。
Burg maximum entropy spectral estimation theory of modern spectral estimation is introduced in this paper, and the PSD (Power Spectral Density) is simulated by VC + + . At the same time, Burg is compared with Bartlett of classical spectral estimation, and the choice of position is analyzed. The conclusion is that FPE (Finally Predication Error) is to be used for optimal choice of position.
