中文说明：
ICA(独立成分分解),可实现采集信号中源信号的分离，便于提取特征量，实现模式识别。同时由于可以将源信号分离开来，可实现信号的降噪，去掉基波、三次谐波、五次谐波等。
English Description：
ICA (independent component decomposition) can realize the separation of the source signal in the collected signal, which is convenient to extract the feature quantity and realize the pattern recognition. At the same time, because the source signal can be separated, the signal noise can be reduced, and the fundamental wave, the third harmonic and the fifth harmonic can be removed.
