为了更有效地提取脑电信号特征波,结合小波包技术,提出了一种脑电特征波提取方法。首先对脑电信号进行小波包分解,然后进行相关频段信号的重构,从而提取出特征波,并对其进行功率谱分析和能量计算。实验结果表明,小波包技术能有效地提取脑电信号特征波。
A method which used wavelet package is put forward to extract the feature of EEG signals more efficiently.With the help of wavelet package the original EEG signals are firstly decomposed and then recomposed at the related frequency range.Analyze the power spectrum and energe after that.The experiment result shows that the wavelet package can extract the feature waves efficiently.
