Patent ID: 7646238

Claim:
An amplification apparatus comprising: a transmission data power value calculation unit for calculating a power value of digital transmission data to be transmitted; a transmission data modifying unit for modifying the transmission data based on compensation data; a transmission signal generation unit for generating an analog transmission data from the modified transmission data; an amplification unit for amplifying the transmission signal while imparting predetermined characteristics to the same; and a distortion detecting unit for detecting distortion of the amplified transmission signal; a compensation data table changing unit for changing values in a compensation data table used for generating the compensation data based on the detected distortion; and a compensation data unit for generating the compensation data based on the calculated power value of the transmission data and the values in the compensation data table, wherein the compensation data table changing unit carries out a first perturbation method or a second perturbation method using the detected distortion of the transmission signal and the values in the compensation data table to change the values in the compensation data table, wherein the first perturbation method is a perturbation method using a power series, and the second perturbation method is a perturbation method based on an interpolation using representative values.
