    摘要: A frequency synchronization apparatus includes: a correlating unit that obtains a first correlation value by correlating a known reference guard interval of an OFDM symbol and a reference copy interval corresponding to the reference guard interval, and obtains a second correlation value by correlating the estimate guard interval and an estimate copy interval corresponding to the estimate guard interval; a determining unit that compares the first and second correlation values to determine a first case where the first correlation value is larger by a pre-set magnification than the second correlation value, a second case where the second correlation value is larger by a pre-set magnification than the first correlation value, and a third case which is not the first case nor the second case; and a frequency offset estimating unit that estimates a frequency offset by using a correlation value corresponding to any one of the first to third.

    摘要: The present invention relates to a door assembly and refrigerator having the same. The door assembly according to the present invention includes a door main body, a panel disposed on a front surface of the door main body, and a side cover coupled at least one of a left side portion and a right side portion of the door main body and supporting the panel, wherein the side cover is provided with screw coupling portions concaved from an external surface and protruded from an inner surface along an insertion direction of screws and screw holes formed by penetrating the screw coupling portions, and the door main body is provided with inference-avoiding space portions for receiving the screw coupling portions therein. Accordingly, it is capable of preventing inferiority of the side cover and of reducing the amount of used materials.
