Abstract

A predistortion system for optimizing the performance of a distorting component. The predistortion system comprises a signal generator, the distorting component, an analyzing device for frequency and/or time domain analysis, and a predistortion device. The signal generator generates a first signal according to a reference signal. Furthermore, the first signal after being passed through the distorting component results in a second signal. Then, the second signal after being passed through the analyzing device results in a third signal. Moreover, the third signal after being passed through the predistortion device results in a compensated signal. In addition to this, the reference signal is provided for the predistortion device.
