Zusammenfassung:	A bio radar system using an OFDM(Orthogonal Frequency Division Multiplexing) signal is provided to overcome deterioration of performance by overcoming noise and interference. A bio radar system using an OFDM carrier includes an OFDM transmitter and receiver structure. The bio radar system further includes an adaptive filter for separating a transmission signal from a received signal, and a low pass filter and a band pass filter for separating a heartbeat and respiration signal from a detected complex heartbeat and respiration signal. The bio radar system utilizes the OFDM signal in order to overcome noise and interference. The bio radar system extracts a reflected signal of a pure target from a mixed reception signal.
