A New Channel Model Based on Multiconductor Transmission Line Theory for Broadband Over Distribution Grids

The ordinary power line communications systems has being faced the hostile channels encountered in low voltage distribution grids. One of the possible resolutions maybe the implementation of the multiple inputs systems, which can use the multiple conductors in the grid networks. In this paper, a new channel model dedicated to the multiple input systems was constructed. The signals distributions on different conductors are derived in detail. The proposed channel model is of the format of the reflection matrix and includes the inner sources and loads. The comparison was performed and a good agreement between the measurements and the simulation result can be found
