The design of the indoor integrated power line communication(PLC）and visible light communication(VLC) requires study on the reference model of integrated systems. Since the traditional analytical model of the integrated channel of PLC and VLC does not determine the parameters of the channel model, it can only describe general characteristics of the channel qualitatively. We propose a reference model of the integrated PLC and VLC systems through the actual measurement of the integrated channel in the typical scenario, and the reference model is determined by a small set of parameters. The model parameters are fitted based on the least squares method, and the practicability of the integrated channel is improved by the obtained parameters. We then set up a test network to verify the correctness of the model, and the results show that the proposed model can significantly describe transfer characteristics of the hybrid system.
