Time synchronization in OFDM systems

Orthogonal Frequency Division Multiplexing(OFDM) is a modulation using multicarrier, it can effective resist Inter Symbol Interference(ISI).In this paper, a symbol synchronization scheme is presented, It is a modification for Schmidl and Cox,s.The two methods are analysed and compared. Through the result of compareison,we can see that the modified scheme is easier to synchronize.
