Claim One:
1. A method of estimating a data sequence transmitted using a Viterbi algorithm, comprising the steps of: (a) storing sampled values of incoming data at a predetermined time interval in a first memory; (b) retrieving a plurality of sampled values from said first memory; (c) retrieving a plurality of receive signal replica coefficients previously prepared and stored in a second memory; (d) determining a plurality of receive signal replicas by multiplying said plurality of sampled values retrieved in step (b) by said plurality of receive signal replica coefficients retrieved in step (c); (e) determining branch metrics using said sampled values of the incoming data and said plurality of receive signal replicas determined in step (d); and (f) estimating a data sequence using said branch metrics according to the Viterbi algorithm.
