Abstract
A state metric calculator for calculating state metrics of stages in a trellis of a sequence estimation technique is described. The calculator has a processing path containing operations needed for calculating a state metric of a trellis stage from state metrics of an earlier trellis stage. One or more data stores are located in the processing path to divide the path into separate sections. The sections can then operate on the production of different state metrics to one another in, if desired, the same clock cycle.
