| Abstract: | The paper illustrates an OFDM synchronization method of pilot superposition, and the estimate time offset and frequency offset is realized with the well serf-relativity of PN sequence. Under the condition of multiplexor channel, the paper implements the synchronization through Matlab simulation. Then, it utilizes the chip made by Altera Company to finish the hardware design of OFDM on the tool platform of Quartus II 5.0. Finally, the circuit design is simulated. |
