摘　　要：介绍了电力线用做通信介质时高频部分的特性 ,以及应用于高速宽带电力线通信的 OFDM(正交频分复用 )调制的基本原理 ;分析了 OFDM应用于电力线通信的性能 ,并与其他调制技术进行了比较 ;结合一个典型应用的例子 ,介绍了国际上研究的最新进展。The paper introduces the characteristics of high frequency bands of power line which can be used as a high speed communication channel. The basic principle of OFDM (orthogonal frequency division multiplexing) modulation for high speed broadband power line telecommunication is described. The performance of OFDM used in power line is also analyzed. The comparison between OFDM, QPSK, FSK and CDMA is given. Combining a typical practice example, the latest overseas development is provided.
