碩士 === 國立中興大學 === 通訊工程研究所 === 105 === In this thesis, we know that OFDM system has the better transmission rate and spectrum efficiency than traditional FDM systems, but synchronization is a sensitive problem to OFDM system. We introduced the method about timing synchronization and frequency synchronization. Implementing the OFDM system’s transceiver in Simulink, and using time domain channel estimation method to reform the frequency domain channel estimation. In multipath channel, the time domain channel estimation method has the better ability to resist the noise than frequency domain channel estimation method in low SNR.
