    Abstract: An apparatus for estimating bio-information includes: a sensor configured to obtain a bio-signal from an object; and a processor configured to obtain a second-order differential signal of the bio-signal, to detect at least one of an inflection point in a predetermined period of the second-order differential signal, and a zero-crossing point in the predetermined period of the second-order differential signal, to extract a feature based on the detected at least one of the inflection point and the zero-crossing point, and to estimate bio-information based on the extracted feature.

    Abstract: A heartbeat index determination apparatus may include a pulse wave acquirer configured to acquire a plurality of pulse wave signals that are measured using light of different wavelengths; and a processor configured to measure wavelength-specific heartbeat index values from the plurality of pulse wave signals and determine that a wavelength-specific heartbeat index value that is obtained from the plurality of pulse wave signals a most number of times among the wavelength-specific heartbeat index values is a heartbeat index value of a user.

    Abstract: Provided is a method and apparatus to adaptively set a threshold for signal demodulation. The apparatus and the method include adaptively setting a threshold to demodulate a currently received symbol based on the demodulation value of a previously received symbol based on a comparison value. The comparison value is obtained by comparing a number of previously received symbols having a demodulation value of “0” and a number of currently received symbols having a demodulation value of “1”.
