摘要
An OFDMA radio communication apparatus of the present invention includes a radio transmitter that amplifies a transmission signal by a amplifier; and a distortion compensation unit that generates distortion compensation coefficient data that serve to compensate for non-linear distortion of the amplifier based on a learning signal and inputs a transmission signal obtained by multiplying an OFDMA signal by the distortion compensation coefficient data to the radio transmitter. The device further includes an MAC unit that generates the learning signal and inserts it as a burst signal in a burst region of OFDMA frames to which a burst signal can he allocated so as to generate OFDMA frame data; and a PHY unit that converts the OFDMA frame data into the OFDMA signal of a frequency domain based on a transmission mode of an OFDMA that has been set for the device and inputs it to the distortion compensation unit.
