A Reduced-State Sequence Estimation (RSSE) method is disclosed, whereby states in a trellis structure associated, for example, with a Viterbi algorithm are partitioned into a plurality of hyper-states. During a hyper-state decision interval, a hyper-soft value is calculated. The calculated hyper-soft value is a measurement of the accuracy of the hyper-state decision made. The calculated hyper-soft value can be used by an equalizer to generate soft-value information for decoding. A soft-value generated from such a hyper-soft value combined with bit soft-value in an RSSE algorithm is significantly more accurate than a soft-value that can be generated for a DFSE algorithm (i.e., without such a hyper-soft value).
