While not designed with communication applications in mind, power lines have been attractive targets for providing ancillary services decades. Unfortunately, loads and switchgear can easily interfere reliable both direct subtle ways. Power line (PLC) is therefore often relegated to non-critical control tasks like home lighting or appliance control, where difficulties failure simply result a wal...

The subject of this paper is to analyse the low voltage distribution lines inside the consumer premises, in order to attain a channel model useful to simulate its behaviour for high bit-rate digital communications. Measurements have also been performed both in the laboratory and in residential buildings, and results are presented and discussed. Finally, some estimations of the channel capacity ...

A broadband metamaterial absorber working in the X-band is designed and fabricated by 3D printing this study. This structure capable of nearly absorbing power incoming waves (more than 90%) frequency band starting from 7.1 to 13.8 GHz. based on an infinite array conductive ribbons, thickness just 0.1? for minimum (without considering ground layer). circuit model transmission line theory are use...

Distribution Line Communications technology allows the usage of electrical power supply networks for communications purposes and, today, also broadband communication services. The main idea behind DLC is the reduction in operational costs and expenditure for realization of new telecommunications networks. Using electrical supply networks for telecommunications has also been known since the begi...

We describe coding and modulation aspects for a channel with different kinds of a-typical noise disturbances. An example of such a channel is the powerline communication (PLC) channel, but the same noise disturbances can be observed in for instance xDSL communications. The channel is assumed to suffer from background noise, impulsive noise, narrowband noise and fading. In addition, in PLC, the ...
