In the process of signal transmission, noisy signals interfere with normal signals unavoidably.
在信号的传输过程中，噪音信号不可避免地会干扰正常信号。

On the basis, the characteristics called the ICA Energy (ICAE) and the Filtered ICAE (FICAE) are used for the noisysignal endpoint detection.
在此基础上提出了IC A能量(ICAE)和滤波icae (FICAE)特征来进行端点检测。

Wavelet soft-threshold de-noising method was applied to preprocess the noisysignal, and the noise interference in disturbance detection was reduced to a great extent.
