说明： 本文设计了一个基于IFFT/FFT算法与802.11a标准的OFDM系统，并在计算机上进行了仿真和结果分析。重点在OFDM系统设计与仿真，在这部分详细介绍了系统各个环节所使用的技术对系统性能的影响。在仿真过程中对OFDM信号使用QPSK调制，并在AWGN信道下传输，最后解调后得出误码率。整个过程都是在MATLAB环境下仿真实现，对ODFM系统的仿真结果及性能进行分析，通过仿真得到信噪比与误码率之间的关系，为该系统的具体实现提供了大量有用数据。
(In this paper, an OFDM system based on IFFT / FFT algorithm and 802.11a standard is designed and simulated on computer. The emphasis is on the design and Simulation of OFDM system. In this part, the influence of the technology used in each link of the system on the system performance is introduced in detail. In the simulation process, the OFDM signal is modulated by QPSK and transmitted in AWGN channel. Finally, the bit error rate is obtained after demodulation. The whole process is simulated in Matlab environment. The simulation results and performance of ODFM system are analyzed. The relationship between SNR and BER is obtained through simulation, which provides a lot of useful data for the specific implementation of the system.)
