PROBLEM TO BE SOLVED: To acquire a radio communication device capable of maintaining an accurate frame synchronization, even if an SW(sync word) cannot be detected continuously due to decrease in reception signal level or interference from other stations. SOLUTION: The configuration of this radio communication device comprises an SW pattern holding/selecting unit 2 which selects an SW pattern corresponding to a slot in reception based on a count value outputted from a reception timing generation counter unit 7, a comparison unit 4 which compares the received data with the selected SW pattern and outputs correlation pulses by a timing that satisfies a prescribed condition, an aperture control unit 5 which sets a detection range of correlation pulses for an allocated slot, and sets a detection range of correlation pulses for a subsequent slot if correlation pulses cannot be detected at the allocated slot, a load value determining unit 6 which corrects a count value shift due to frequency deviation with a clock installed at a base station, and the reception timing generation counter unit 7. |
