    • A Viterbi decoder with a pipeline processing function for decoding a received code sequence transferred from an encoder, including correlation determining circuit for calculating correlation between a received code sequence and each of a plurality of predetermined code sequences of known allowable transitions; and selecting circuits operatively receiving the correlations for selecting one of the predetermined code sequences as the maximum likelihood transition. The selected one of the predetermined code sequences has the maximum correlation among the correlations. A decoded code sequence is obtained from the selected one of the predetermined code sequences. The correlation determining circuit includes a plurality of new correlation determining circuits each for determining a new correlation based on newly received code sequence and an aready calculated correlation between the already received code sequence and one of the predetermined code sequences; and a comparing circuit for comparing, simultaneously with the determination of the new correlations, already calculated correlations between the already received code sequence and the predetermined code sequences, so as to output a path selecting data. The selecting circuits selects, in response to the selecting data, one of the predetermined code sequences as the maximum likekihood sequence with respect to the code sequence generated by the encoder.
