Claim Text:
1. An in-band data communication apparatus using a wireless power, the apparatus comprising: a modulating unit configured to modulate data by mixing a predetermined signal and pulse signal-type data; a demodulating unit configured to detect reflected power generated due to impedance mismatching between a source resonator and a target resonator, and to demodulate received data based on a variance of the reflected power, wherein the received data is modulated using a variance of the reflected power by the target resonator; a source resonance unit configured to transmit transmission power including the modulated data to the target resonator, and to receive the reflected power; and a controller to control the pulse signal-type data, and to control impedance matching between the source resonator and the target resonator, wherein the demodulating unit comprises: a low-pass filter configured to block a harmonic signal from the detected reflected power.
