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.

Abstract: A method of receiving data includes sampling the data at data sampling points to obtain data samples corresponding to information contained in the data, and sampling the data at intermediate sampling points between the data sampling points to obtain intermediate samples. The data is corrected at at least one intermediate sampling point of the intermediate sampling points depending on at least one of a previous data sample sampled at a data sampling point preceding the at least one intermediate sampling point and a previous intermediate sample sampled at a data sampling point preceding the at least one intermediate sampling point.

Abstract: A detector for a receiver generates a clock phase detection signal and a carrier phase detection signal from of a plurality of clock polyphase signals of an oversampled signal. The detector comprises a plurality of carrier phase detectors, a plurality of variance estimation units, a selection unit and an output unit. Each phase detector determines the carrier phase of a clock polyphase signal and emits a carrier phase signal corresponding to the carrier phase. Each variance estimation unit determines the variance of one of the carrier phase signals. The selection unit compares the variances of the carrier phase signals with one another and emits a selection signal as the clock phase detection signal for selection of that clock polyphase signal whose associated carrier phase has the smallest variance. The output unit emits at least one of the carrier phase signal as the carrier phase detection signal.
