AI Technical Summary
It is difficult to effectively filter out high-frequency noise and low-frequency noise in pulse signals with existing technologies, and the characteristics of the signal itself may be damaged during the noise reduction process.
The pulse signal is decomposed to obtain multiple frequency components, and adaptive selection is performed based on the frequency of each frequency component to remove the high-frequency noise of the low-frequency signal and the low-frequency noise of the high-frequency signal respectively. Finally, reconstruction is performed to obtain the denoised pulse signal.
It effectively filters out high-frequency and low-frequency noise in the pulse signal, retains the characteristic information of the signal to the maximum extent, and improves the signal-to-noise ratio and signal recognition accuracy.
