Abstract
The disclosed data processor develops a data signal which has a plurality of multi-level symbols. The data processor, in response to each of the symbols, determines the lowest path metric characterizing the data signal, and selects one of a plurality of sets of slice values in response to the lowest path metric. A slicer responds to the selected set of slice values by slicing the multi-level symbols. There may be only two sets of slice values in the plurality of sets of slice values, wherein each of the only two sets has three slice levels. Alternatively, there may be only five sets of slice values in the plurality of sets of slice values, wherein each of the only five sets has five slice levels. As a still further alternative, there may be only two sets of slice values in the plurality of sets of slice values, wherein each of the only two sets has a minimum of six slice levels.
