| Abstract: | The design of reliable high speed communication systems for power line communication (PLC) requires an accurate knowledge of such channel specific characteristics as attenuation, impedance and noise. On the basis of experiments, the channel characteristics are studied. The preconditions for system design based on PLC are described and channel models are developed for reflecting the main characteristics of typical transfer functions to evaluate the capacity of channels. The schemes for noise handling and channel reconstructing are discussed. |

| Keywords: | power line communication channel noise attenuation impedance time variation |
