The indoor access network is characterized by several branches that cause many reflections. In this paper, we present an approach to model the transfer function of electrical power lines for broadband power line communication. The assuming channel consists of three wires, which is widely used in many countries. As an application of the proposed method, the effect of line length from transmitter to receiver, branched line length and number of branched are also studied. From the frequency

Figure 8. Phase response for medium voltage channel with 1 branch (a); 5 branches (b); 10 branches (c); and 15 branches (d). The peak points in the frequency responses tend to fluctuate as number of distributed branches increases. The study of these phenomena is crucial for improving the performance of the PLC channel.
