Digital Signal Transmission on Power Line Carrier Channels: An Introduction

The possibility of transmitting digital signals on power line carrier channels is investigated. An accurate model of the multiconductor transmission line and a rigorous propagation algorithm are used. A computer aided procedure is presented to evaluate transient response to any input digital signal code. The discrete convolution method uses the inverse Fourier transform of the channel frequency response in amplitude and phase. The eye diagram approach permits evaluation of channel performance. The results obtained in an application on a 3-phase long line confirm the feasibility of the proposed method.
