    Author: Wu X, Feng H, Zhou H, Wang T.
    Journal: Sheng Wu Yi Xue Gong Cheng Xue Za Zhi; 2001 Mar; 18(1):60-3. PubMed ID: 11332117.
    Abstract:
    In this paper, we discuss the relation between matched filter and wavelet transform(WT), and point out that wavelet transform is just the matched filter with changeable detection template. According to this idea, the method of signal detection based on hybrid wavelet transform (HWT) is proposed. HWT in this paper means that in WT decomposition and reconstruction, we use two different mother wavelets. One is used as a changeable template for the pulses detection and the other is used for the characteristic enhancement of detected pulse. This method has been applied to the interference pulse detection in EEG signal. The experiment result shows that HWT has the good property for instantaneous signal detection.
