- Disclosed is a symbol synchronization obtaining apparatus robust to a frequency offset in a cell search of a wireless communication system. The symbol synchronization obtaining apparatus robust to a frequency offset in a cell search of a wireless communication system may include a sequence generator to generate a base sequence for obtaining the symbol synchronization, a synchronization pattern generator to generate a modified sequence based on the base sequence, and to generate a synchronization pattern by combining the modified sequence and the base sequence, a frequency mapping unit to perform mapping of transmission information to a time area and a frequency area, based on the synchronization pattern, for generating a transmission frame, and a transmitting unit to transmit the transmission frame.
