Abstract

A method of detecting a heart rate using a photoplethysmography (PPG) signal with a removed motion artifact includes receiving, by a heart rate measurement device, a PPG signal and an acceleration signal; converting, by the heart rate measurement device, the PPG signal and the acceleration signal into signals in a frequency domain; calculating, by the heart rate measurement device, a difference between the PPG signal and the acceleration signal in the frequency domain and obtaining a PPG signal with a removed motion artifact; and estimating, by the heart rate measurement device, a heart rate based on the PPG signal with the removed motion artifact.
