Power line communication integrated in a Wireless Power Transfer system: A feasibility study

In this work a characterization of a Wireless Power Transfer (WPT) system as a possible channel for data communication is presented. The frequency response of a real WPT system based on the principle of magnetic resonance coupling is simulated accurately using a lumped equivalent circuit model. The theoretical channel capacity of the channel is calculated as a function of the coupling coefficient of the WPT system, in the presence of additive white Gaussian noise. Furthermore, a general design architecture is presented for embedding a broadband powerline communication, BPLC, system on a WPT system.
