| Zusammenfassung: | An error detecting device for received digital data is provided which solves a problem of a conventional device in that error detection following the Viterbi decoding performed on most important bits cannot detect all errors if they include a considerable amount of errors. The present error detecting device includes a Viterbi decoder (4) for carrying out the Viterbi decoding of the received digital data, an error number decision portion (5) for comparing a threshold value with the number of errors of the path metric obtained by the Viterbi decoding, and a voice decoder (6) for decoding the received digital data, on which the error number decision portion (5) decides that the number of errors is below the threshold value. |
