  • Abstract
    This paper considers the time and frequency synchronization based on the interspersed pilots. The shortcoming of an existing algorithm is observed, and a new channel estimation assisted time and frequency algorithm is proposed. Since the channel estimation is always needed by the data transmission, our newly proposed algorithm can improve the synchronization performance without too much increase in the complexity. The simulations prove the effectiveness of the newly proposed algorithm.
