METHOD FOR RADIO PHYSIOLOGICAL SIGNAL BIOMETRIC AND RADIO PHYSIOLOGICAL SIGNAL SYSTEM USING THE SAME

摘要

A method and a system for wirelessly measuring a biological signal are provided to improve accuracy of the biological signal by transmitting the biological signal without using an electrode which is attached to a human body. A signal receiver(310) divides an original signal using a coupler, generates an LO(Local Oscillator) signal, transmits a transmission signal to an object through an antenna, and receives a reflected measured signal from the object. An LNA(Low Noise Amplifier)(320) amplifies the measured signal. A mixer(330) removes a leakage component from the original signal by using the LO signal, so that the measured signal is extracted. A transmission module(350) converts the measured signal to a digital signal and delivers the digital signal to an analysis server. A BPF(Band Pass Filter)(360) generates at least two biological signals from the digital signal from the analysis server. A biological signal measuring result display unit(370) displays a measuring result by using the generated biological signal.
