The indoor power line channel model based on two-port network theory

This paper presents a channel model of the indoor power line for broadband power line communication (BPLC). Considering transmission theory, the two-port network model of power line has been established in this paper. And according to this model, characteristics of power line channel under the different network configuration and terminate loads have been analyzed. The model has been verified with practical measurements on actual power network. It is demonstrated that the model based on two-port network theory can accurately reflect the situation of power line channel. And the result shows that the characteristic of channel is variation with frequency and network topology.
