摘　　要：本文对电力线信道的传输特性进行了分析,对适合电力线通信的载波技术进行了论述,着重对电力线载波通信部分的载波调制carrier modulation技术进行了研究,提出了OFDM(Orthogonal Frequency Division Multiplexing)技术作为家居网络电力线通信网关的数字通信,最后,给出了电力线作为传输介质家居网络的具体方案。The transmission property of power and power line carrier communication has been line channel has been analysed in this paper, expounded too. The author emphasizes on the analysis of carrier modulation technology about power line carrier communication, and puts forward the OFDM technology as Numeral Communication to Power Line Carrier Home Network, finally, gives out the concrete scheme of home network based on power line as the transmission medium.
