【摘要】 对低压电力线信道的衰减特性进行了研究,采用多径传输模型分析多径延时与多径传播造成的衰减的原因,依据均匀传输线理论分析了线路损耗造成的衰减的原因,并推导出电力线衰减的传输函数.根据传输函数建立电力线网络多径传输模型,并进行MATLAB仿真,得到的仿真曲线与实测曲线大体一致.更多还原

【Abstract】 Research the low-voltage power line channel attenuation characteristics,adopted multi-path transmission model to analyse the reason of multi-path delay attenuation and multi-path propagation attenuation,based on the uniform transmission line theory to analyse the reason of line losses attenuation,and derived the transmission function of power line attenuation.Build the multi-path transmission model of power line network based on the transfer function,and use MATLAB simulation.The simulation curve is broadly consistent with the measured curve.更多还原
