providing at least one amplifier circuit configured to assume one operating state from a set of a first operating state and at least one second operating state, with the first operating state and the at least one second operating state being characterized by at least one characteristic variable;

providing a discrete-value and discrete-time modulation signal with a first component and a second component;

providing a first table comprising a plurality of predistortion coefficients;

providing at least one second table comprising a plurality of predistortion coefficients;

producing a power word derived from an output power of a transmission signal or from the first component;

determining the operating state of the at least one amplifier circuit with recording of the characteristic variable;

comparing the power word with a reference value and producing a first result or a second result depending on the comparison;

selection of one table from the first and the at least one second table depending on the determined operating state;

selecting a predistortion coefficient from the selected table depending on the power word and the first component when the comparison has produced the first result; and

distorting at least one component of the first component or the second component with the predistortion coefficient when the comparison has produced the first result.
