Abstract
A communication apparatus including a first unit which performs sampling of a synchronization pattern included in a signal with multiple clocks having different phases and identifies clocks where a predetermined synchronization pattern could be correctly sampled, from among the multiple clocks; a second unit which identifies, from among the multiple clocks, a first and second clock having a first clock edge which is nearest to the time point at which the data of the synchronization pattern changes and a second clock edge which is second nearest to the time point next to the first clock edge, respectively, the first and second clock edges being where the sampling of the synchronization pattern is performed; and a judgment section which judges one of clocks other than the first and second clocks, among the clocks with which the predetermined synchronization pattern was correctly sampled, to be used for sampling of the signal.
