摘　　要：电力线载波通信以电力传输线为信道,实现数据传递和信息交换。针对低压电力线载波通信信道所处的环境噪声干扰特点和衰落特性,探讨了符合我国实际情况的典型信道传输模型。仿真结果分析表明,该模型可以较好地模拟实际电力线信道环境,为进一步开展电力线载波通信的研究提供了理论依据。Power line carrier communication （PLC） uses power line as communication medium to transmit data and information. With the advantage of wide coverage, data transmission via power line has great economic benefit and bright application prospect. Based on the noises and fading characteristic of low-voltage power line channel, this paper discusses the typical channel model conforming to the situation in China. Simulation results show that the model can better simulate the actual power line channel enviromnent. It provides a theoretical basis for the further development of power line carrier communication.
