ABSTRACT:
In a receiving apparatus for receiving communication data from a transmitting apparatus, specific code patterns are inserted in the communication data at predetermined intervals. The receiving apparatus includes a first frequency difference measurement device for measuring a first frequency difference between a receiving clock of the receiving apparatus and a transmission clock provided to the communication data, based on one of the specific code patterns and another of the specific code patterns which is positioned later; and a frequency adjustment device for adjusting a frequency of the receiving clock based on the measured first frequency difference so that the frequency substantially coincides with a frequency of the transmission clock.
