  • Patent number: 8089990
    Abstract: Disclosed are an apparatus and a method for preventing data read error for OFDM symbol demodulation. An average time synchronization offset estimating unit estimates average time synchronization offset between a pilot symbol of a time synchronized data frame and pilot symbols of data frames next to the time synchronized data frame. A data buffer control unit acquires a start location of a data frame to be read using the estimated average time synchronization offset, and controls reading of written data frames using the acquired start location information of the data frame to be read. In the apparatus and the method, a data buffering using a ring buffer construction may compensate time synchronization offset of samples containing real data in an OFDM symbol and prevent an erroneous read error in order to improve a receiving performance of a receiver.
