PROBLEM TO BE SOLVED: To optimally and flexibly calculate a correction value for canceling carrier leak and image. SOLUTION: On the basis of a correction value calculated by a correction value calculation means 3, a correction means 1 corrects the carrier leak and image of a transmission signal. A modulation means 2 modulates the transmission signal outputted from the correction means 1. The correction value calculation means 3 calculates a correction value to be corrected by the correction means 1 on the basis of the transmission signal outputted from the modulation means 2. When no transmission signal is being transmitted, a test signal output means 4 outputs to the correction means 1 a test signal for calculating the correction value of the correction value calculation means 3.
