    • A method is proposed for signal processing with predistortion. An amplifier circuit is provided for this purpose, whose operating states are characterized by at least one characteristic variable. A digital modulation signal having two components (R, φ), as well as a power word (LS), derived from the first component (R), are produced, and an operating state of the at least one amplifier circuit is then determined by recording of the characteristic variable. The power word (LS) is compared with the reference value and used to decide whether to predistort the first and/or the second component. A table with various predistortion coefficients is selected from at least two tables, depending on the operating state of the amplifier circuit. One predistortion coefficient is then determined from the selected table with the produced power word (LS) and the first component (R), and the predistortion coefficient is used for predistortion.
