DISTORTION COMPENSATION DEVICE AND DISTORTION COMPENSATION METHOD

摘要

PROBLEM TO BE SOLVED: To improve amplification efficiency.SOLUTION: A distortion compensation device 110 includes a calculation section 111 and a correction section 112. The calculation section 111 calculates a transient response of a power supply circuit 121 on the basis of a predictive value of current consumption of an amplifier 122 based on a signal to be amplified by the amplifier 122 and of a desired value of supply voltage from the power supply circuit 121 to the amplifier 122 based on the signal to be amplified. The correction section 112 corrects the signal to be amplified which is to be input into the amplifier 122 on the basis on a difference of the transient response calculated by the calculation section 111 from the desired value.
