Abstract:
This paper proposes a novel estimation scheme of the timing offset for orthogonal frequency division multiplexing transmission over multipath fading channels. We first design an impulse-like correlation function and obtain the sample standard deviation of the correlation values, and then, develop a decision metric based on the reciprocals of the sample standard deviations for the timing offset estimation, which has the maximum value when the timing offset is estimated correctly. Unlike the conventional schemes, the proposed scheme exploits the change in statistics by the first-arriving path rather than the magnitude itself of the first-arriving path. Numerical results show that the proposed timing offset estimation scheme offers a performance improvement over the conventional schemes in various multipath fading channels.
