Abstract

We develop a general channel model in broadband power-line communications (BPLC) network using infinite geometric series and the description matrices. The developed general channel model can handle arbitrary PLC channel links easily; thus, we can calculate accurate channel characteristics without increasing computing complexity. For considering the effect of the various branches of the network, we investigate the characteristics of the channel links with adjacent nodes composed of multiple branches. We conduct the simulations by varying the degree of distantness of the adjacent nodes and the number of branches at the nodes. Our simulation results suggest that we should consider adjacent nodes with a degree of distantness up to one for the arbitrary channel links; these were not considered in previous studies. This enables us to calculate accurate channel responses of the arbitrary channel links of indoor BPLC networks.
