In a method for reducing RFI interference in a DMT data transmission a compensation signal for the purpose of reducing an RFI interference signal superposed on a transmitted DMT reception signal is generated. Only carrier frequencies of the DMT reception signal in the vicinity of the interference frequency of the interference signal which are not utilized for the data transmission are used, at least one normalized complex spectral function for all the carriers of said interference signal is provided, an FFT for the purpose of obtaining spectral values of said DMT reception signal is carried out, and an observation window to a current DMT frame of the DMT reception signal is assigned. A complex evaluating coefficient for the current DMT frame is calculated and the complex evaluating coefficient resulting from the spectral values of said DMT reception signal within the observation window and the complex evaluating coefficient are identical for all frequencies within the current DMT frame. The compensation signal is calculated by multiplying the normalized complex spectral function with the complex evaluating coefficient.
