%X This paper proposed a fast, simple, robust and precise scheme of frequency offset estimation within a great range with lower SNR in the context of the Synchronized Multi-Carrier CDMA plus (SMCC ) system, which is one of the candidate standard of digital terrestrial multimedia/TV broadcasting transmission in China, and COFDM systems based on short Pseudo Noise sequence (PN-sequence) reconstructed by a special method. Computer simulation results show the proposed technique get better properties than the conventional synchronization techniques in AWGN, one- and two-tap Rayleigh fading channels even with lower SNR over -20dB. In addition, the estimation range of frequency offset could be widened to half bandwidth. Obviously, the proposed scheme is much better than the conventional frequency synchronization method.
