PROBLEM TO BE SOLVED: To shorten the time to compensate for an Idq drift.SOLUTION: A transmission device includes a digital signal processing device for computing a first distortion compensation coefficient on the basis of a signal amplified in a first amplifier, setting a first reference range of the distortion compensation coefficient used for performing distortion compensation on a signal yet to be amplified on the basis of a power of an unamplified signal and the first distortion compensation coefficient, computing a second distortion compensation coefficient on the basis of a signal amplified in a second amplifier, setting a second reference range of the distortion compensation coefficient used for performing distortion compensation on the signal yet to be amplified on the basis of the power of the unamplified signal and the second distortion compensation coefficient, and calculating a correction factor for correcting the second compensation coefficient on the basis of the first and second reference ranges. |
