Abstract

A decoding device includes: an interference canceling circuit () which extracts, from states of 2-number (where K is a natural number) of detected signals that are likely within a range of K bit width where an interference between bits of the digital information occurs due to predetermined frequency characteristics, most likely 2-number (where M is a natural number) of detected signals respectively corresponding to states of 2-number of detected signals which exist within a range of M bit width that is included in the range of K bit width; and a Viterbi decoding circuit () which generates a decoded signal by calculating differences between the 2-number of detected signals extracted by the interference canceling circuit () and expectation signals respectively corresponding to the 2-number of detected signals and also by selecting a transition sequence of a state of a detected signal for which the calculated difference is smallest.
