Abstract: A motion artifact detecting method using wavelet transform which is capable of removing the problem caused by a radio noise and a motion artifact generated during the measurement of a PPG signal which is one of bio-signals, the method including: measuring a PPG signal; generating a signal obtained by removing a radio noise from the measured PPG signal; setting a reference signal from the signal from which the radio noise is removed; selecting a base signal based on the set reference signal; performing wavelet transform using the base signal; and detecting and removing a motion artifact using the wavelet-transformed value.
