A Viterbi equalizer can provide an accurate equalizing characteristic. This Viterbi equalizer comprises a synchronizing signal data detecting circuit for detecting a synchronizing signal data portion from a reception signal data series, a transmission line characteristic estimating circuit for modelling an impulse response between a transmitter and a receiver by comparing a synchronizing signal data detected by the synchronizing signal data detecting circuit with a reference signal, and a decoding circuit for decoding a transmission data series by using a Viterbi algorithm on the basis of a transmission model obtained from the transmission line characteristic estimating circuit.
