Abstract
A communication device that compensates a distortion of a transmission signal, amplifies the compensated transmission signal by an amplifier, and outputs the signal. The device includes a storage unit that stores a transmission characteristic of a transmission power of the communication device, a correcting unit that calculates a power value at a set transmission frequency by referring to the storage unit and that corrects a feedback signal of the transmission signal amplifier by the amplifier based on the calculated power value and a maximum transmission power defined by the communication device, and a calculating unit that calculates a distortion compensation coefficient based on the transmission signal and the feedback signal corrected.
