Abstract:
1. A digital predistortion linearizer comprising a transmission unit and a reception unit, wherein the reception unit receives a first signal comprising a transmission signal transmitted from the transmission unit and a distortion signal generated in the transmission unit 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, and wherein the predistortion signal is generated by adjusting the phase of an initial transmission signal input to the transmission unit to the phase of the first signal by delaying the initial transmission signal, and removing the initial transmission signal.
