基于电力线的宽带接入技术

Research on Broadband Access Technology Based on Power Line

电力线通信(PLC)作为一种新型的宽带接入技术,由于其可以使用丰富的电力线资源实现数据通信和工业应用,因而具有广阔的社会价值和经济价值。围绕宽带电力线通信的接入原理,分析了其作为通信信道的优缺点;然后介绍了2种用于宽带电力线通信的关键技术:扩频技术和正交频分复用技术;最后对宽带电力线通信的应用前景进行了展望。

As a new type of broadband access technology, the power line communication （PLC） has wide social value and economic value because it can use the rich resources of power lines for data communications and industrial applications. Based On the principle of broadband power line communication technology, this paper analyzes its advantages and disadvantages as a channel. Then it describes such two key technologies for broadband power line communication as spread spectrum technology and orthogonal frequency division multiplexing. Finally, the application prospect of broadband power line communication is described.
