摘要：
A distortion compensating apparatus has an IQ imbalance compensation coefficient arithmetic circuit 31 for calculating, from correlation values of a transmission signal and a feedback signal, IQ imbalance compensation coefficients for compensating for IQ imbalance in a quadrature modulator 23; and an IQ imbalance compensator 21 for compensating for the IQ imbalance with respect to a distortion compensated signal output from a distortion compensator 11 according to the IQ imbalance compensation coefficients, and for outputting to the quadrature demodulator 23.
