A simple timing offset estimation method for orthogonal frequency division multiplexing (OFDM) systems as a modification to Schmidl & Cox’s method  is presented. By designing the training symbol, the timing metric plateau inherent in  is eliminated and hence performance is im-proved. The performances of the proposed method and  are evaluated by computer simulation in terms of estimator vari-ance. The timing offset estimator of  is also included in the performance comparison as another reference. The simulation results show that the proposed method achieves significantly smaller estimator variance. Using more samples in calculation of half symbol energy required in timing metric is shown to give more robustness against dispersive channel
