| Abstract: | 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. |
