Abstract
In accordance with a rate detecting method for detecting a predetermined rate at which a received signal has been coded, the coded signal is decoded based on a first synchronizing signal having a frequency corresponding to a first rate such that a first decoded signal (ST11) is generated and then it is judged whether or not synchronization is determined for the first decoded signal (ST12). If the synchronization cannot be determined, there is generated only a second synchronizing signal having a frequency corresponding to a second rate having a difference between itself and a first rate which is smaller than a permissible value of the rate determined by the lower and upper values of the rate (ST13, ST17).
