Orthogonal Multi-Carrier Modulation(OMCM) is adopted to overcome the frequency selectivity and time variation of low-voltage powerlinechannel.
为克服低压电力线信道的频率选择性和时变性,系统采用正交多载波方式传输信息。

The characteristics of powerlinechannel are the foundation of designing the low voltage powerlinecarrier communication system.
低压电力线信道特性是设计低压电力线载波通信系统的基础。
