Abstract:The research of power line channel emulator can help researchers to avoid a large number of repeated and time-consuming outdoor test experiments, save a lot of manpower and resources, shorten the development cycle, and speed up the development of power line communication technology. This paper, based on the System Generator platform, designs a multi-node low-voltage broadband power line channel simulator and implements it through FPGA. The channel emulator includes AD sampling module, signal processing module and DA output module, which can emulate the channel between multi-nodes in the power line network and meet the needs of two-way communication of the channel. Through the comparison between the theoretical data and the measured data, the results show that the power line channel emulator can emulate the corresponding broadband power line channel fading according to the actual power line scene.
