摘要
A method and apparatus of estimating a data sequencetransmitted using a Viterbi algorithm, are disclosed.Sampled values of incoming data are acquired at apredetermined time interval into a memory. Subsequently,a plurality of sampled values are retrieved from saidmemory. Further, a plurality of receive signal replicas,which have been previously prepared and stored in anothermemory, are retrieved. A plurality of receive signalreplicas are determined by multiplying the sampled valuesby the receive signal replica coefficients. Branchmetrics are then determined using the sampled values ofthe incoming data and the receive signal replicas. Adata sequence is estimated using said branch metricsaccording to the Viterbi algorithm.
