Abstract: A biosignal processing method includes receiving a biosignal from a sensor, performing first signal processing based on variable frequency complex demodulation (VFCDM) on the biosignal, performing, once or more, second signal processing based on the VFCDM on a periodic signal having an instantaneous frequency as a center frequency, the instantaneous frequency being calculated based on the first signal processing, and estimating bio-information, based on at least one processing signal calculated based on the second signal processing performed once or more.
