ABSTRACT:
A synchronous pattern detection section checks coincidence between a predetermined reference synchronous pattern and a bit pattern included in a data stream. Each time a bit pattern which coincides with the reference synchronous pattern is detected, the synchronous pattern detection section extracts a frame length of a data frame corresponding to the bit pattern which is detected, and stores the extracted frame length in a storage section. Each time a bit pattern which coincides with the reference synchronous pattern is detected in the synchronous pattern detection section, a synchronization determination section determines whether or not the bit pattern detected by the synchronous pattern detection section is a correct synchronous pattern, based on a plurality of frame lengths stored in the storage section and a bit length of a data stream which is obtained after detection of the bit pattern. With this structure, a synchronous pattern included in the data stream can be detected with higher precision.
