摘　　要：OFDM技术以其具有的抗窄带干扰和抗频率选择性衰落等优点,被4 G和5 G采用为核心技术,代表了未来无线通信的发展方向。本文通过对OFDM技术的研究,以Xilinx FPGA为硬件平台,基于IEEE802.11a协议设计了OFDM接收系统的FPGA实现方案。测试结果表明,该接收系统能够正确恢复出经过干扰的信号域和数据域信息,并在FPGA上实现,对OFDM系统的硬件实现具有重要的参考意义。OFDM technology is used as the core technology of 4 G and 5 G because of its advantage ofnarrow- band interference as well as frequency selective fading, and it represents the developmentdirection of wireless communications in the future.Through studying the OFDM technology, with XilinxFPGA as the hardware platform, a FPGA implementation scheme of OFDM receiving system is designedwhich is based on the IEEE802.11a protocol. The test results show that the receiving system cancorrectly recover the data which is disturbed in signal domain and data domain, and implemented inFPGA, which has important reference meaning for the hardware implementation of OFDM system.
