A robust timing synchronization method for OFDM system
In this paper, we proposed a robust timing synchronization method for OFDM systems using an antenna array, where the effect of carrier frequency offset (CFO) was eliminated by the crossed product of the array signal vector with a single conjugate element signal of the array. The synchronization timing estimation was realized under the least square criterion. Simulation results demonstrate that the proposed method is robust in the presence of CFO and the co-channel interference signals.
