Research on the channel characteristics of low-voltage power line

摘要

Because the Low-voltage broadband power line communication (BPLC) has the advantages of less investment costs, high construction speed and accessing easily, it becomes a development hotspot of the future cable communication. Compared with the other wired communication mediums, the low-voltage power line channel is more instable and has stronger interferences, which become the fundamental reason to limit the development of low-voltage power line communication. By combining the domestic and international research on low-voltage power line channel, this paper analyzed the multi-path effects and noise characteristics of the low-voltage power line channel. The low-voltage power line channel and noise were modeled and simulated numerically. The specific simulation results were provided, which can be a technical reference for the design of PLC system.
