摘要：
A radio communication device includes a power amplifier to amplify a transmit signal, a control unit to generate a voltage control signal for defining power to be supplied to the power amplifier in accordance with a conversion curve expressed using a polynomial series based on an envelope signal obtained from the transmit signal and determine the polynomial series based on an efficiency of the power amplifier, and a power source unit to supply the power to the power amplifier based on the voltage control signal, wherein the control unit divides an amplitude range of the envelope signal on the conversion curve into a plurality of sections and determines the polynomial series based on at least one of the plurality of sections.
