| Zusammenfassung: | The invention relates to an arrangement and method for enhancing a search through a trellis in connection with decoding or channel correction, for instance. When searching through the trellis, the state indexes being processed are divided into more than one subset at each stage of the trellis, the path metrics of the state indexes are defined in the subsets, and a predefined number of state indexes are selected for continuation from each subset on the basis of the metrics. |
