ABSTRACT:
The present invention includes: a synchronous-word detecting unit receives a baseband received signal including a synchronous word and data for each frame, and detects whether or not the synchronous word is coincided with an expected value in the baseband received signal by using an N-(N is an integer of 2 or larger) phase sampling clock; a phase information retaining unit retains phase information accumulatively including results detected for a plurality of frames by the synchronous-word detecting unit, and determines a phase to be sampled on the basis of the retained phase information; a phase selecting unit selects and determines a phase of the sampling clock on the basis of determination by the phase information retaining unit; and a FIFO buffer samples the data from the baseband received signal, and outputs the sampled data.
