Abstract: A wireless communication device includes a table, a correction unit, a digital-to-analog converter (DAC), a power amplifier, an analog-to-digital converter (ADC), a calculation unit, and an update unit. The table stores distortion correction coefficients, each corresponding to a different amplitude level of a transmission signal.

The power amplifier amplifies the analog signal. The ADC converts the amplified signal into a digital signal. The calculation unit calculates a distortion correction coefficient candidate based on the transmission signal and the digital signal. The update unit updates the distortion correction coefficient stored in the table based on the distortion correction coefficient candidate, so long as the number of times the transmission signal is input to the correction unit is not greater than a threshold.
