Branched-bus HF power-delay-profile approach of indoor PLC channels

Abstract

In this paper, the branched-bus topology is evaluated as representative of indoor PLC channels' multipath fading properties. The path amplitude and arrival-time distributions are investigated, as well as ranging of the RMS-delay-spread. Specific analogy between the simplified topology and real indoor power-line network structures is hereupon introduced. The evaluation is performed via comparative simulation between channel routes of a real in-house network and the corresponding branched-bus configurations. A novel computational simulation tool is to this effect employed. Qualitative suitability of the examined topology is indeed verified, and quantitative deductions are extracted as well.
