摘要
阐述了一种导频叠加的OFDM同步方法,利用具有良好的自相关性PN序列实现时偏和频偏估计。在多径信道条件下,通过Matlab仿真能较好地实现同步。然后利用Altera公司的芯片在Quartus Ⅱ 8.0工具平台上实现了OFDM同步的硬件设计,最后进行了电路仿真。
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.
