ABSTRACT:
A method and a device for reducing the crest factor of a signal is operable to generate a correction signal as a combination of a plurality of partial correction signals having respectively predetermined frequencies and a signal having a reduced crest factor being issued as a differential between the correction signal and the signal. The respectively predetermined frequencies are selected such that the correction signal, which has a period length that is shorter than a length of the signal, is periodic. Therefore, according to the invention, only one period of the correction signal is determined and the correction signal is then determined as a periodic continuation of the one period.
