A calibration apparatus for a quadrature modulation system with a quadrature modulation compensator and a logarithmic envelop detector, wherein a parameter update of the quadrature modulation compensator is derived by utilizing a transformed offset value and a transformed gain value of the logarithmic envelop detector as intermediate parameters, and the transformed offset and the transformed gain parameters are used in a training sequence of the quadrature modulation compensator.
