    摘要: 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.

    摘要: In a method for error correcting a data signal that is transmitted via a channel and contains data blocks with associated error checking information, the data signal is first equalized, with calculated soft-bit information. In a subsequent step, the error checking information is evaluated with respect to the data block. If the evaluation of the error checking information shows that a single bit error is present in one message bit, the single bit error is corrected only when a condition that is dependent on the soft-bit information is satisfied.
