A method for clipping a baseband input signal filters the complex baseband input signal with a function H<SUB>1 </SUB>for forming a filtered first signal. To form a clipped signal in the baseband the filtered first signal is multiplied by a scaling factor. By a signal analysis of the filtered first signal signal overshoots are predicted from which the scaling factor is determined for the baseband clipping. The filter function H<SUB>1 </SUB>is calculated as the quotient from a frequency response H<SUB>S </SUB>of a transmission filter used one the one hand and from an error frequency response H<SUB>F </SUB>on the other hand, with the error frequency response H<SUB>F </SUB>being determined in such a way that the error spectrally shaped with H<SUB>F</SUB>, which arises for the limitation of the baseband signal, a frequency-dependent tolerance is not exceeded. Subsequently the clipped signal is filtered with the error frequency response H<SUB>F </SUB>for forming a filtered second signal.
