Abstract

A method for equalization of a signal is provided, wherein the equalization is of a signal that is transmitted via a data channel based on the DF method. The method takes account of at least one interference channel, and includes processing of at least two trellis diagrams in each time unit, with the states of at least one of the trellis diagrams describing the data channel. A DF contribution that is used for processing of this trellis diagram includes information about at least one interference channel.
