中文说明：利用OFDM的特性，设计调制解调，基于labview平台搭建仿真系统，进行OFDM系统的仿真。然乎可以与USRP 硬件设备连接，实现真实设备间的收发信号。
English Description：
Using the characteristics of OFDM, the modulation and demodulation is designed, and the simulation system is built based on LabVIEW platform to simulate the OFDM system. However, it can be connected with USRP hardware devices to realize the receiving and transmitting signals between real devices.
