Abstract: The present disclosure provides a noise detection method and a noise detection apparatus. The method includes: segmenting a collected photoplethysmography signal into a plurality of sub-signal segments; extracting a characteristic of each sub-signal segment; for each sub-signal segment, determining a self-similarity of the sub-signal segment in the photoplethysmography signal based on the characteristic of the sub-signal segment; and determining that the sub-signal segment is noise when the self-similarity is lower than a threshold.

Abstract: The present disclosure provides a wearable device, a signal processing method and a signal processing apparatus, the signal processing method is applied to the wearable device, the wearable device is provided with a biosensor and a motion detector group, and the signal processing method includes the following steps. The human physiological signal collected by the biosensor is acquired, the human physiological signal is divided into multiple signal frames, each of the multiple signal frames corresponds to the time range; for each signal frame, it is determined whether the user wearing the wearable device is in the body motion state according to the body motion signal collected by the motion detector group within the time range corresponding to the signal frame, and when the user wearing the wearable device is not in the body motion state, the signal frame is stored into the preset buffer.
