A wireless communication apparatus includes: a processor that performs distortion compensation on a transmission signal by using a distortion compensation coefficient; an amplifying unit that amplifies the transmission signal; and a feedback path that feeds back a feedback signal to the processor. The processor executes a process including: acquiring, from a transmission signal at a first timing and feedback signals at a second timing that is before the first timing and at a third timing that is after the first timing, instantaneous delay associated with propagation delay of the feedback signals in the feedback path; calculating a mean value of the instantaneous delay acquired in a predetermined time period; adding delay associated with the calculated mean value to the transmission signal; and updating the distortion compensation coefficient by using the transmission signal to which the delay is added and the feedback signal.
