ABSTRACT:
A method and a device for determining an output sequence of output elements from an input sequence of input elements is provided, the method or the device being implemented according to a decision feedback equalizer. The adaptation of coefficients of the equalizer is performed on the basis of an estimated error determined as a function of a scaling (a, c0). According to the invention the scaling (a, c0) is determined such that it differs from a nominal input value by a deviation value during transmission without symbol interference. The deviation value is dependent on non-compensatable inter-symbol interference.
