Abstract: PURPOSE: An apparatus and a method for obtaining coarse synchronization of an OFDM/CDMA(orthogonal frequency division multiplexing/code division multiple access) system are provided to obtain coarse synchronization by detecting a pilot symbol interpolated into a signal frame. CONSTITUTION: An apparatus for obtaining coarse synchronization of an OFDM/CDMA system consists of an FFT(fast Fourier transform,117), a pilot symbol detector(317) and a synchronization obtaining unit. The FFT(117) processes a received digital signal into plural sub-carriers and the pilot symbol detector(317) detects a pilot symbol interpolated into a signal frame. The synchronization obtaining unit obtains coarse synchronization by the maximum correlation of the detected pilot symbol. For coarse synchronization, the pilot symbol is detected from the FFT-processed frame signal by the plural sub-carriers. Therefore, a loop for the coarse synchronization is simplified and frequency offset is removed to keep orthogonality between the sub-carriers regular.
