A radio apparatus receives a received signal having a frame structure with a synchronization word field interposed between anterior half part data and posterior half part data. The radio apparatus includes: a storage unit that sequentially stores predetermined time length of detected wave data; a synchronization detecting unit that detects a synchronization word from the detected wave data; a symbol timing detecting unit that determines a symbol timing of the detected wave data from the synchronization word; a DC offset detecting unit that detects a DC offset in the detected wave data from the synchronization word; and a data reproducing unit that extracts detected data for every symbol timing from detected wave data of the anterior half part data at a time when the synchronization word is detected, and cancels the DC offset from the detected wave data for every symbol timing so as to extract a symbol value. |
