According to the invention, during the transmission of data by multi-carrier modulation, the data is combined to form blocks on the transmitter side and is modulated in blocks by Inverse Discrete Fourier Transformation (IDFT). Several carriers, which are not occupied by data, are reserved and these carriers are occupied in such a way as to generate a large amount of temporal functions, which after filtration exhibit Dirac-like characteristics. Said temporal functions are generated in such a way that the Dirac-like temporal functions obtained after filtration reach their maxima in an oversampled temporal resolution of different, preferably adjacent positions. Both the oversampled Dirac-like temporal functions after filtration and the corresponding filter input functions that have not been oversampled are stored and a pair is iteratively selected from the pairs of stored temporal functions or filter input functions. Said pair is displaced to the position of a peak value resulting from a data occupation of the remaining carriers, inclusive of iterative modifications that have already taken place, and is subsequently subtracted from the temporal signal after being weighted using a factor, the iterative modifications being applied in parallel to the temporal signal in the oversampled grid after filtration and to the corresponding temporal signal without oversampling and without filtration. |
