ABSTRACT:
A device reduces the dynamic range of a signal at a first point along a signal processing direction in a transmitter of a communication system. The device includes an input to which an input signal is applied, a correction prediction device, a delay device, an addition device, and an output. The correction prediction device generates a predictive signal based on the input signal which represents the prediction of the signal at the first point, and generates a correction signal from the predictive signal. The delay device generates an input signal delayed by a delay from the input signal, the delay taking into consideration the processing time in the correction prediction device. The addition device subtracts the correction signal from the delayed input signal in order to generate a corrected signal. The output provides the corrected signal at a second point in front of the first point.
