Li Xucheng, Yang Luping, Zhang Zhengping. An improved OFDM symbol synchronization algorithm based on training sequence[J]. 2007,(6):54-56. DOI: 10.13756/j.gtxyj.2007.06.016.
Synchronization is a key technology in OFDM applications.The training sequence-based Schmidl&Cox(S&C) synchronization algorithm is studied
which is improved in view of its high estimation error by adding the calculation points and smoothing the maximum value.MATLAB simulation and analysis show that although the calculation amount is somewhat increased
fluctuations of the symbol synchronizations are effectively reduced and the synchronization performance remarkably improved in low SNR.
