Abstract
A transmission device includes: a transmission signal amplifier enabled to vary transmission power; a transmission power control unit 28 that controls the transmission power; an error rate characteristic estimation unit that estimates an error rate of a reception signal in a reception device of a communication partner, and a reception unit that receives information on an SNR in the reception device. The error rate characteristic estimation unit executes: processing of estimating a constellation corresponding to a modulation scheme and reflecting a specification regarding an input-output characteristic of the transmission signal amplifier on the basis of the transmission power, and processing of estimating the error rate on the basis of a characteristic of the constellation and the SNR. The transmission power control unit controls the transmission power such that the error rate satisfies a predetermined requirement.
