Abstract: PURPOSE: A wireless energy and data transceiver and a method thereof are provided to form a resonator and a radiator into one body by using multiplied frequency several or several tens of times power transmission frequency for far-field communication. CONSTITUTION: Energy with frequency f0 is transmitted to a resonator(206) via a power amplifier(202) and a first matching circuit(204). The energy transmitted to the resonator is delivered to a receiving-side resonator(300) using resonation and used as power source for a load or communication module of a receiving device(104). A data signal generated from a communication module(208) is mixed with a return frequency signal provided from a local oscillator(210) through a frequency mixer(212). The mixed signal is amplified through a signal amplifier(214) and transmitted to a radiator(218) through a second matching circuit(216). The transmitted signal is received by a receiving-side radiator(308).

Abstract: Provided is a digital predistortion linearizer applicable to millimeter-wave band point-to-point communications. The digital predistortion linearizer includes a transmission unit and a reception unit. The reception unit receives a first signal including a transmission signal and a distortion signal through a millimeter-wave propagation environment, detects the distortion signal from the first signal, and transmits information on the detected distortion signal with the first signal to the transmission unit. The transmission unit generates a predistortion signal using the information on the distortion signal and the first signal received from the reception unit, couples the generated predistortion signal with the transmission signal, and outputs the coupled signal.
