A digital signal decoding device according to an aspect of the present invention is a digital signal decoding device for generating a binary code sequence by maximum likelihood estimation from a convolutionally encoded input signal sequence, includes an add-compare-select unit configured to compare only two metric values one unit time before the calculation time of a predetermined branch metric value calculated from the input signal sequence at two successive times at each time, to add the predetermined branch metric value to the two metric values independently of the compare process, to select one of the two sums in accordance with the comparison result of the two metric values, and to output the selected value as a metric value to be used at the next time.
