本文概述了电力线通信，它最初是为了将电力从少数来源输送到大量接收器而设计的。最初，第一次数据传输是通过电力线进行的，主要是为了在发生故障时保护配电系统的部分。本文还研究了用于高比特率应用的电力线的性能。HomePlug标准采用的是DMT技术，理论上可以提供100Mb/S的数据速率。然而，基于该标准的产品只能达到14Mb/S的数据速率。为了防止电力线信道中严重的噪声和衰落，需要提供非常高的差错控制编码水平。HomePlug联盟的努力和家庭网络技术在美国的增长预示着基于DMT的PLC家庭网络的非常光明的未来。
This article overviews the power line communication, which is originally devised to transmit electric power from a small number of sources to a large number of sinks. Initially the first data transmission were over power lines were primarily done only to protect sections of the power distribution system in case of faults. This paper also studies the performance of power lines for high bit rate applications. DMT technology is adopted by the homeplug standard can theoretically provide data rates of 100Mb/s. However, products based on the standard only have achieved data rates up to 14 Mb/s. To protect against the severe noisy conditions and fading in the powerline channel, very high levels of error control coding need to be provided. The efforts of the homeplug alliance and home networking technology's growth in the US portend a very bright future for DMT-based PLC home networking.
