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 non-invasively estimating blood pressure is provided. The apparatus for estimating blood pressure may include a bio-signal measurer configured to measure a bio-signal from a user and a processor configured to estimate blood pressure using the measured bio-signal. The processor may extract a first feature and a second feature from the bio-signal at an extraction time, estimate changes in the first feature and the second feature which have occurred during a time period from a calibration time at which the first feature and the second feature are calibrated to the extraction time at which the first feature and the second feature are extracted, and estimate a blood pressure based on the changes in the first feature and the second feature.
