正交频分复用(OFDM)技术是电力线通信常用的调制技术之一；电力线通信的信道条件复杂，信道特征是电力线通信的重点模块，两者都是电力线通信研究的重要组成部分。在深入研究 OFDM 基本原理和电力线信道特性的基础上，在OFDM 原有的发射与接收模型中，加入了电力线的信道特性，从而建立了相对完整的电力线通信系统模型，并利用 MATLAB对该模型进行仿真，仿真结果体现了电力线信道特性以及 OFDM 技术应用于电力线通信的优越性。

Orthogonal frequency division multiplexing (OFDM)technique is one of the most useful modulation methods of power line communication.The channel conditions of power line communication is complex,and power line channel char-acteristics is the key of the power line communication,both of which are important parts of power line communication re-search.Based on the research of OFDM basic principle and characteristics of power line channel,this paper added the power line channel characteristics into the emission and receiving modules of OFDM model,and built a complete model of power line communication system.The simulation results got by MATLAB showed the power line channel characteris-tics and the advantages of OFDM technology applied in power line communication.
