摘　　要：电力线传输中出现的高噪声、高衰减、高畸变等特性严重影响通信质量.正交频分复用(OFDM)是实现宽带电力线通信的关键技术,有效克服了信道的多径衰落.本文在MATLAB/SIMULINK下建立了仿真模型并进行仿真分析,最后设计了图形用户界面(GUI),通过在界面设置参数来控制系统仿真的过程,这对实现系统仿真的可视化具有一定意义.During power-line translation, the characteristics such as high noise, high attenuation and high distortion etc. affect the communication quality severely. Orthogonal Frequency Division Multiplexing （OFDM） is a key technique for realizing broadband power-line communication, and overcome multipath fading channels effectively. In this paper, a simulation model under MATLAB/SIMULINK is built and simulation analysis is given. Finally, a graphic user interface is designed to control the process of the system simulation by setting parameters in the GUI. which is useful to realize visualization of the system simulation.
