摘　　要：OFDM技术在高速数据传输中得到了广泛的应用。简要介绍了OFDM基本原理,建立了基于Simulink的OFDM系统仿真模型;对系统各种同步偏差的影响进行了分析。基于所建的仿真平台,得出了仿真系统的星座图及误码率曲线,很好的验证了理论分析的结果,证明了仿真模型的有效性。The technology of OFDM has been applied broadly in the transmission of high-speed data. The basic principle of OFDM was illuminated. The system simulation model of OFDM was set up by using Simulink. The effects of Synchronization errors on the performances were analyzed, and the constellations and the BER curves were given and conformed to the analysis results. It is shown that simulation model is available.
