一种新的最大熵谱近似估计方法

本文提出了最大熵谱估计的一种新方法，由其所获得的自回归系数的估值，使反映前、后向预测误差的能量以及前、后向预测误差与信号之间交关系的一个综合目标函数极小化。仿真结果表明，该法不仅具有良好的估计质量和较小的谱峰位移，而且消除了谱线分裂现象。

A New Method for Maximum Entropy Spectral Estimation

This paper presents a new method for maximum entropy spectral estimation.The respective AR coefficient estimations minimize an objective function which expresses synthetically both the energy of forward and backward linear prediction errors and the orthogonality relation between the prediction errors and the signal.Simulations verify that not only good spectral-estimation performance and small frequency biases are obtained ,but the spectral line splitting phenomenon is also dissipated.
