Abstract
A wireless communication apparatus includes a plurality of antenna elements; a plurality of power amplifiers provided in the plurality of antenna elements; a processor that outputs a transmission signal to the plurality of power amplifiers; and a plurality of feedback paths each of which allows a feedback signal to be fed back from the plurality of power amplifiers to the processor, wherein the processor executes a process for collectively correcting variations in analog characteristics exhibited in the plurality of feedback paths, and a process for updating, by using the transmission signal and the feedback signal that are obtained by being corrected, a distortion compensation coefficient that is used to compensate nonlinear distortion produced in the plurality of power amplifiers.
