Abstract
A viterbi decoder includes a viterbi decoding section which decodes input data, and a coding unit which codes the data decoded by the decoding unit. The number of bit error corrections in the output of the coding unit during a measurement period which is set externally are detected. Further, a synchronized state is detected based on the detected number of bit error corrections and a threshold. A threshold detecting unit detects the threshold from the detected number of bit error corrections during a threshold detection period that includes the measurement period.
