摘　　要：在低压电力线上实现高速数据传输具有广阔的应用前景和经济价值,但是由于电力线信道存在着随机的高噪声、多径效应和信道衰落,严重制约了高速数据的传输。OFDM(正交频分复用)是解决这个问题的最有效手段之一。论文介绍了低压输电线上数据传输的特性、OFDM的基本原理和实现方法,以及用Systemview仿真软件对其调制解调过程进行仿真的结果。Highspeed data communication over lowvoltage power line is an active field with broad application perspective and economic benefits in the world. But due to the stochastic high noise,multipath effect and attenuation,power line channel is difficult for transmitting highspeed streams. Orthogonal frequency division multiplexing(OFDM) is one of the technologies for resolving this problem. This paper presents the characteristics of data communication over lowvoltage power line,the principle and implementing method of OFDM and simulating the process of the modulation and demodulation of OFDM with Systemview.
