ABSTRACT:
An error detecting device and method for use when applying the Viterbi decoding to an inputted signal, when it is necessary to derive the number of errors included in a decoded signal. A value of a path metric derived upon the Viterbi decoding is read out and outputted as the number of errors. Two kinds of decoding devices, each reading out a value of a path metric and outputting this value as the number of errors, are provided for a sound signal and an FACCH signal. A signal is inputted to both devices for decoding, respectively. The numbers of errors derived from both devices are compared, and it is judged based on a result of the comparison, whether the inputted signal is the sound signal or the FACCH signal.
