Abstract:
1. A method for determining an output sequence of output elements from an input sequence of input elements, formed by transmission of a send sequence via a transmission channel, in which inter-symbol interference occurs, the method comprising: providing an input sequence of input elements from the transmission channel to a processor; combining each input element with a respective correction element, to form a corrected input element, wherein a first part of the inter-symbol interference is configured to be corrected by the correction element and a second part of the inter-symbol interference is configured to not be corrected by the correction element; forming a respective output element of the output sequence as a function of the corrected input element; forming a respective estimated error as a function of the corrected input element, the respective output element and a scaling; characterizing a deviation between the corrected input element and the respective output element scaled with the scaling; forming the respective correction element as a function of a coefficient and an output element preceding the respective output element; adapting the coefficient as a function of an estimated error allocated to the output element preceding the respective output element; determining the scaling such that the scaling differs from a nominal corrected input element, with full correction of all the inter-symbol interference, by a value dependent on the second part of the inter-symbol interference; and providing the output sequence from the processor to another transmission channel.
