ABSTRACT:
An adaptation apparatus for adapting an input signal, the input signal being digital in the frequency domain and having a peak-to-average-power-ratio in the time domain. The adaptation apparatus has an evaluation unit for evaluating the input signal and for providing an evaluation signal based on an optimization criterion. The adaptation apparatus further has a summing unit for adding the evaluation signal to the input signal in the frequency domain and for providing an output signal in the frequency domain having a lower peak-to-average-power-ratio in the time domain than the signal in the time domain.
