Abstract
There is provided a communication apparatus capable of reducing power consumption. The communication apparatus in accordance with the present invention includes a synchronization detection blockwhich detects synchronization by performing a receiving process using a plurality of clocks whose phase differs from each other with respect to synchronization information contained in a first frame as well as identifies the synchronization detected clocks as candidate clocks to be selected; a clock phase selection blockwhich selects a sampling clock to be used for sampling of the transmission signal from the candidate clocks to be selected, selects a stop clock separated by a predetermined phase from the selected sampling clock, and outputs an instruction for the stop clock; and a clock gate unitwhich, terminates supplying the stop clock from the plurality of clocks to the synchronization detection blockas well as supplies other clocks to the synchronization detection block. In the process of receiving a second frame following the first frame, the synchronization detection blockdetects synchronization from the clocks other than the stop clock.
