在本文中,把自回归(AR)谱估计法应用于体表胃电信号的分析;而AR模型的阶次由最终预测误差(FPE)判据确定。初步的实验表明,体表胃电信号的AR谱分析结果是较为满意的。
In this paper, the autoregressive (AR) spectral estimation method is applied to the analysis of body surface electrical signals, while the order of the AR model is determined by the final prediction error (FPE) criterion. Preliminary experiments show that the surface of gastric electrical signal AR spectrum analysis results are more satisfactory.
