Abstract：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 frequency synchronization method.
