Research on Multi-node Broadband Power Line Channel Modeling

Multi-level relay routing is widely applied in power line communication, both the physical layer and routing strategy performance relies on power line communication channel between different nodes. The conventional point-to-point power line channel model is no longer fit for system performance test. Based on the two-port model, this paper proposes a multi-node broadband power line channel modeling method. In the proposed method, the low voltage power line network is divided into sub-networks. This method can calculate the power line channel frequency response between any two terminals of the low-voltage distribution network. The comparison between the measured channel response and the theoretical simulation results shows that the proposed method can accurately describe the multi-node power line channels and the correlation characteristics between different channels.
