Abstract :
In this paper, the introduction of several OFDM synchronization algorithm is proposed first, then a new symbol timing and frequency synchronization algorithm using repeated training sequence is presented. This algorithm can improve the performance of the estimation through the multi-path fading channel. At the end, the simulation of this algorithm is given according to multi-path channel, and the performance is proposed.
