The invention relates to a method for equalizing a receive signal in a digit al receiver with the aid of a decision feedback equalizer structure. The receiv e signal is based on a one dimensional signal constellation (e.g. BPSK, GMSK, OQPSK) or a signal constellation which can be transformed in such a manner. The coefficients of the DFE are fixed in such a manner that the expected val ue of the squared real part of the error of the receive signal is minimized. As opposed to prior art, the complex value error is not used as a basis for optimization. Calculation is much more limited to real value. The filter coefficients can also have a real value instead of a complex value. The fundamental aspect of the invention is that it is possible to improve the performance of the DFE structure in a basically simple manner. Even computational complexity can be reduced in comparison with prior art.</SDOAB >
