摘　　要：利用已有的中压电力线路实现长距离通信以解决我国偏远农村的通话和上网问题有着极其巨大的社会和经济效益。但迄今为止,在中压电力线路上进行的研究工作非常少。为了获得中压线路的信道特性及其相应的模型,本文介绍了一种基于全数字DQPSK调制的中压电力线信道测试系统的设计,并给出了该系统在我国农村中压10KV电力线线路上的测试结果。Long distance power line communications over medium vokage power distribution networks has a broad application and prospect in the vast rural areas of China. But only a few researches have been done on medium voltage power lines. In order to obtain channel characteristics as well as its model of a medium voltage power line, this paper presents a designing scheme of a DQPSK-based measurement system and field measurement results on a typical 10KV medium voltage power line in rural areas of China.
