Orthogonal frequency division multiplexing systems are much more sensitive to timing and frequency error, therefore there were several methods to estimate time and frequency offset. In the thesis, a novel timing offset estimation method for OFDM systems is proposed, it transmits a specific training symbol in the time domain at transmitter. At the receiver, it estimate the timing offset by using a specific timing metric. The proposed scheme isn¡¦t affected by the frequency offset compare with Zhang¡¦s method, and it can estimate timing offset more accurately than Schmidl¡¦s method and Minn¡¦s method. We will analyze the statistical characteristic of the timing metric we proposed at correct time. According to the analysis and simulation result, it can show the accuracy of our analysis. Finally from the simulation result, it demonstrates that the proposed scheme has better performance.
