Abstract
A distortion compensation apparatus that compensates for distortion of an amplifier is provided. The distortion compensation apparatus includes: a distortion compensation processing section that performs a predistortion process for a signal provided to the amplifier, based on an amplifier model of the amplifier, and outputs a compensated signal; an estimation section that estimates the amplifier model; and a filter. The estimation section estimates the amplifier model, based on the compensated signal and a monitor signal obtained by monitoring an output of the amplifier. The monitor band of the monitor signal provided to the estimation section is narrower than a frequency band of the compensated signal. The filter is provided so as to eliminate an influence of a signal component outside the monitor band among signal components of the compensated signal, on the estimation of the amplifier model by the estimation section.
