低压电力线的信道特性

Channel Characteristics of Low Voltage Power Line

为了很好地利用电力线进行载波通信 ,分析了低压电力线的时变特性、阻抗特性、衰减特性和噪声特性等信道特性 ,实测了各种特性的波形。同时 ,针对这些特性 ,就怎样克服其不利因素 ,给出了相应的措施。实验结果表明 :要在低压电力线上实现较为理想的通信 。

In order to make good use of power line carrier to communicate, it is necessary to analyze the time-variable, impedance,attenuation and noise characteristics of low voltage power line. The waves of every characteristic have been experimented. At the same time, aiming at these characteristics, some available measures are given in order to conquer the disadvantage factors. The experimental results show that some suitable carrier communication modes must be adopted to realize ideally the carrier communication on low voltage power line.
