A transmission device includes a first amplifier, a second amplifier, and a digital signal processor configured to calculate first distortion compensation coefficients based on a first amplified signal obtained by amplifying an input signal by the first amplifier, set a first distortion compensation coefficient reference range used to perform distortion compensation on the input signal based on power of the input signal and the first distortion compensation coefficients, calculate second distortion compensation coefficients based on a second amplified signal obtained by amplifying the input signal by the second amplifier, set a second distortion compensation coefficient reference range used to perform distortion compensation on the input signal based on the power of the input signal and the second distortion compensation coefficients, and calculate a correction coefficient for correcting the second compensation coefficients based on the first distortion compensation coefficient reference range and the second distortion compensation coefficient reference range. |
