The synchronism judgment apparatus of the invention enables judgment of establishment of synchronization with accuracy compared to a conventional example as long as the above standard is reliably given or identified. Therefore, in a communication system to which the invention is applied, it is possible to maintain the transmission quality and the service quality high and flexibly adapt to a variety of communication services and transmission rates, and the transmission information quantity that may vary to a large extent.
