Abstract
The invention relates to a transmitter comprising: means for generating an intermediate frequency signal, means for predistortion of the intermediate frequency signal using a predistortion parameter, means for generating a radio frequency signal from the predistorted intermediate frequency signal, means for determining an image-to-signal-ratio of the radio frequency signal, means for adaptation of the predistortion parameter for reduction of the image-to-signal-ratio.
