摘　　要：室内电力线通信PLC和可见光通信VLC融合系统的设计需要对融合系统的参考模型进行研究。传统的电力线通信和可见光通信融合信道的分析模型没有对融合系统的信道模型参数进行确定,因此模型只能定性地描述融合信道的一般特性。通过对典型场景下融合信道的实际测量,提出了电力线通信和可见光通信融合系统的参考模型,该模型由一小组参数决定。基于最小二乘法对模型参数进行拟合,进而得到融合信道模型参数,继而增加了融合信道模型的实用性。搭建的融合系统验证了参考模型的正确性,结果表明所提出的融合信道模型能很好地描述实测的融合信道传输特性。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.
