Zusammenfassung:	Disclosed are a wearable multichannel photoelectric pulse wave measuring device using a singular value decomposition (SVD) and a method for removing noise from a signal using the same. According to an aspect of the present invention, the method for removing noise from a signal in a wearable multichannel photoelectric pulse wave measuring device comprises: a step of simultaneously collecting a plurality of PPG signals measured at different measurement sites by a sensing part; a step of removing noise by applying a cut SVD to the collected plurality of PPG signals; and a step of measuring a heart rate in the noise-removed signal. 본 발명은 특이값 분해를 이용한 웨어러블 멀티 채널 광전용적맥파 측정 장치 및 이를 이용해 신호에서 잡음을 제거하는 방법을 개시한다. 본 발명의 일 측면에 따른 웨어러블 멀티 채널 광전용적맥파 측정 장치에서의 신호에서 잡음을 제거하는 방법은, 센싱부가 서로 다른 측정 지점(site)에서 측정된 다수 개의 PPG 신호를 동시에 수집하는 단계; 상기 수집된 다수 개의 PPG 신호에 절삭된 특이값 분해(SVD)를 적용하여 잡음을 제거하는 단계; 및 상기 잡음이 제거된 신호에서 심박수(heart rate)를 측정하는 단계;를 포함한다.
