碩士 === 國立雲林科技大學 === 電子與資訊工程研究所碩士班 === 91 === This thesis aims at frequency synchronization in OFDM systems. This techniques is very sensitive to the frequency offset and time error. The degradation of performance results from the intercarrier(ICI) and intresymbol(ISI). First we focus on estimate the time and frequency offset in OFDM systems. These methods is simulated and analyzed by computer. Finally, We propose frequency estimation: ESPRIT. We conduct extensive experiments to examine several synchronization methods for in-depth exploration into wireless communications systems.
