利用MATLAB软件对OFDM系统做出仿真。仿真中采用QPSK调制技术，并加入高斯白噪声，最终得到QPSK星座映射图以及BER曲线图。由仿真结果可以看出，OFDM在高斯信道具有良好的抗噪声性能，误码率较低。(MATLAB software is used to simulate the OFDM system. In the simulation, QPSK modulation technology is used, and Gauss white noise is added, and the map of the QPSK constellation and the BER curve are finally obtained. It can be seen from the simulation results that OFDM has good anti noise performance and low error rate in Gauss channel.)
