A joint timing synchronization and channel estimation algorithm is proposed for Orthogonal Frequency Division Multiplexing (OFDM) system. In the proposed scheme, the shift delay characteristic of synchronization sequence is revealed in channel estimation process. Through utilizing this characteristic, the correct Symbol Timing Offset (STO) is jointly optimized with channel estimation via the Minimum Mean Square Error (MMSE) criterion. Simulation results demonstrate that the proposed scheme could bring almost ideal performance improvement for both channel and timing offset estimation.
