Abstract: A method and apparatus provide for stable signal demodulation in a communication system. The method and apparatus includes including detecting an erroneous demodulation value based on backward-demodulation of received signals, using a difference between a received signal to be demodulated and a preceding signal of the received signals and correcting the error demodulation value. Alternatively, backward-demodulation is used to confirm received signals.

Abstract: An apparatus for estimating bio-information, the apparatus including a pulse wave sensor and a processor. The pulse wave sensor includes a plurality of channels, each channel of the plurality of channels being configured to measure a first pulse wave signal of a first wavelength and a second pulse wave signal of a second wavelength that is different from the first wavelength. The processor is configured to: for each channel of the plurality of channels, generate a first oscillogram based on the first pulse wave signal, generate a second oscillogram based on the second pulse wave signal, and convert a phase delay between the first oscillogram and the second oscillogram into an area. The processor is further configured to determine a channel among the plurality of channels based on the area of each channel, and estimate bio-information based on the determined channel.

Abstract: A device, a method, and a system recognize a motion using a gripped object. The motion recognition device may estimate a state of a wrist of a user according to a writing action using the gripped object and may estimate a joint motion of a body part related to the wrist according to the writing action. The device may then estimate a state of the gripped object according to the state of the wrist and the joint motion. Additionally, the motion recognition device may control an external device by using a control signal generated by continuously tracking the state of the object.
