Abstract: Provided is a method and apparatus for acquiring OFDM synchronization even when it fails to detect a plurality of symbols at an initial stage. In the method, a frequency is adjusted to a first frequency band and a cross correlation value between a received preamble symbol and a preset preamble symbol is calculated.

When the reexamined cross correlation value larger than the predetermined reference value is detected, timing synchronization, frequency offset estimation, and frame detection are performed.
