| Summary: | 碩士 === 南台科技大學 === 通訊工程研究所 === 98 === The Orthogonal Frequency Division Multiplexing (OFDM) system is a crucial modulation technique in wireless communications, because of its robustness on combating the multi-path fading. However, the OFDM system is very sensitive by the synchronization error. In this paper we propose a rapid symbol timing recovery algorithm base on the common Maximum Likelihood (ML) algorithm. From the simulation results, it demonstrates that our proposed algorithm achives a superior performance in searching the symbol timing.
