Abstract
A wireless communication apparatus configured to amplify a transmission signal at an amplifier and transmit the amplified transmission signal, the wireless communication apparatus includes a memory configured to store a distortion compensation coefficient for compensating a distortion characteristic of the amplifier, and an electrical-power measuring unit configured to measure electrical power of the transmission signal. The wireless communication apparatus includes a gain control unit configured to calculate a gain adjustment value for correcting the distortion compensation coefficient stored in the memory based on a power value measured by the electrical-power measuring unit, and a distortion-compensation processing unit configured to perform distortion compensation on the transmission signal based on the distortion compensation coefficient stored in the memory and the gain adjustment value.
