The Simulation Stualy of Low-Voltage Power Line Carrier Communication Channel Characteristics
摘要
Abstract
In view of the frequency selective attenuation existing in power line carrier communication channel of low-voltage distribution network, established PLC channel models and analyzed the channel frequency response at 50 Hz~20 MHz. As the power line channel existed multipath effects, considering the impact of channel paths to signal attenuation, estab-lished a multi-path channel attenuation model and simulated the signal frequency characteristics in multi-path channels. Obtained the experimental results consistent with the expected. Improved the PLC communication channel and inserted a pilot symbol in OFDM subcarriers channel of the system. The simulated bit error rate of the improved system reduced by 10%than before.关键词
