AMPLIFICATION DEVICE AND RADIO COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an amplification device and a radio communication device at low cost.SOLUTION: An amplification device 1 includes: a distortion compensation unit 3 for performing distortion compensation on an input signal x of an amplifier 2 by means of digital signal processing; and a separation unit 9 for separating an output signal of the amplifier 2 into an I signal as an analog signal component including phase information of the output signal and an analog signal component including power information of the output signal. The distortion compensation unit 3 performs the distortion compensation for the amplifier 2 on the basis of one-bit signals respectively representing with one bit the analog I signal and the analog signal component including the power information of the output signal.
