A novel signal propagation model for power line communication systems

In this paper, we present a scheme for power line communications systems which could use four or five conductors in low-voltage distribution grids. For improving the system capacity and SNR, we propose a channel model based on the multiconductor transmission line theory. The signal distribution on the multiconductors is the function of the reflection matrix with inner source load matrix and load matrix. The signals with such format will be very useful in power line communications system. The measurements have been performed and the comparison between the measurements and simulations verifies the proposed model
