摘　　要：论文对基于OFDM技术的电力线通信系统进行了计算机模拟。在模拟过程中 ,主要针对采用OFDM技术在实际通信过程中可能出现的问题 ,提出解决方案。从模拟结果来看 ,OFDM技术与电力线通信系统中传统的单载波调制技术或扩频技术相比 ,性能更优异 。This paper describes a powerline communication system based on OFDM technology,and presents the result of the system simulation in PC.When OFDM technology is employed in the powerline communication,the important problem,such as power peak to mean ratio,synchronization and interference,are discussed in the paper.The result of the system simulation in PC reveals that there are several advantages of OFDM technology as compared to traditional single carrier or spectrum systems,which are higher bandwidth efficiency and more robust against frequency selective attenuation etc.,and therefore OFDM technology would been adopted as high speed communication in the powerline.
