有小波分解求小波熵，还有小波包技术求解信号特征，适应与分析脑电信号特征-Seeking a wavelet decomposition wavelet entropy, and wavelet packets technique to solve the signal characteristics, and analysis of EEG characteristics of adaptation

小波分解，得到低频系数并求特征熵，可用来对信号进行分选识别-Wavelet decomposition, low coefficient and entropy, which can be used for signal sorting and recognition
