A de-noising method for photoplethysmographic signals based on CoatiOA-VMD-WT

In the process of collecting photoplethysmographic (PPG) signals, it is particularly susceptible to noise from the environment and the object being collected, which can cause a large gap between the collected signal and the true value. In response to this problem, a method for denoising PPG signals...
