Abstract: OFDM is the key technology of 4G in the field of mobile communication. This paper
introduce a method of realizing the synchronization system for broad band data communication based on FPGA, this method provides the indispensable synchronization system for OFDM multi-carriers communication. According to simulation we finish the design of scheme, and then using the CycloneII FPGA of Altera Company realize the whole design of synchronization system. Through testing, demonstrate the feasibility of this scheme.
