Photoplethysmogram simulation

Photoplethysmogram (PPG) simulation is an important sub-task in the field of medical signal processing, aiming to generate simulated PPG signals through computational models. The goal of this task is to accurately reproduce the fluctuations in light absorption caused by changes in blood volume, to evaluate and optimize the performance of medical devices, support physiological parameter monitoring, and disease diagnosis research. Its application value lies in providing standardized test data, promoting algorithm development and validation, and improving the reliability and efficiency of clinical diagnosis.
