Abstract

The power grid provides a readily available medium for communication purposes. This means that the power grid is the cheapest communication medium since no new cabling is required. However, the power grid was designed for the delivery of power and not for communi- cation applications. As such no considerations have been made in the design of power networks to accommodate communication services. However, with the application of current digital signal processing techniques, the power network can be adapted to support communication services. This adaptation requires a full understanding of the power network characteristics, which are noise, distortion and channel effects. These power network characteristics are studied through measurements, modelling and characterization. The results obtained through such studies are then utilized in the redesign of conventional receiver structures and modulation schemes so as to adequately suit them for powerline communication applications. In this paper, we present time domain power line noise measurement results, and then apply a statistical technique for the characterization and modelling of the time domain noise amplitudes in typical indoor power networks. The results obtained are validated through error analysis. The models developed are vital in the optimization of communication applications through the power network.
