PROBLEM TO BE SOLVED: To provide a distortion compensation controller capable of suppressing increase in power consumption.SOLUTION: A distortion compensation controller 1 includes an adjustment section 10 for making the feedback control convergence speed adjustable, at a distortion compensation function unit which performs distortion compensation processing of a transmission signal, for cancelling distortion occurring after amplification of the transmission signal by an amplifier based on feedback control, before being outputted, and outputting the transmission signal subjected to distortion compensation processing while amplifying a predetermined amplification amount. The adjustment section 10 changes the output level of the transmission signal to a desired level, while repeating adjustment of the convergence speed of the distortion compensation function unit, and adjustment of the amplification amount of the amplifier repeatedly.SELECTED DRAWING: Figure 1 |
