1. A method for linearization of a radio frequency high-power amplifier ( 5 ) by means of adaptive digital predistortion of the input signals of the amplifier by determination of correction values, which are approximated from NOMINAL transmission signals, which are detected at the amplifier input, and ACTUAL transmission signals, which are detected at the amplifier output, characterized in that I/Q data, which is derived continuously from the NOMINAL transmission signals in the digital baseband modulator ( 1 ), as well as I/Q data, which is derived from the ACTUAL transmission signals at the amplifier output by means of a measurement device ( 4 ), are supplied to a neural network ( 2 ) for evaluation and for forming correction values, the correction values which are formed are fed back to the digital baseband modulator ( 1 ), and the data stream which emerges from the digital baseband modulator ( 1 ) to the amplifier input is predistorted with the correction values which are formed in the neural network ( 2 ).
