摘要： A method and an apparatus for estimating an offset are provided. The method includes determining one of a frequency offset and a timing offset to be estimated first for pilot symbols detected from a received signal, estimating one of the frequency offset and the timing offset for the pilot symbols according to the determination, compensating for an offset of the pilot symbols based on the estimated offset, and estimating remaining one of the frequency offset and the timing offset which is not estimated for the offset compensated pilot symbols.
