【摘要】：该文提出一种多输入多输出(multi-input multi-output,MIMO)宽带电力线载波通信(power line communications,PLC)信道混合模型。该模型结合电力线载波通信信道自上而下和自下而上两种建模方法,考虑了多输入多输出载波信道的空间相关性,提供一种不需要完整载波网络拓扑信息和测量数据的先验电力线信道建模方法。给出了低压室内电力线载波通信信道模型算例,分析了算例在2~30MHz和2~100MHz两种带宽下的信道特征和参数,并与已有模型进行了对比。结果表明,在同等条件下该文模型与已有模型仿真结果一致,但克服了需要获得大量负载阻抗信息或大量测量数据建模的困难,为多输入多输出电力线载波通信提供了一种具有实用价值的仿真分析方法,对于简化多输入多输出电力线载波信道的研究、设计和工程应用具有重要意义。
[Abstract]:This paper proposes a multi input multi output (multi-input, multi-output, MIMO) broadband power line communication (power line, communications, PLC) channel mixed model. The model combines the power line carrier communication channel top-down and bottom-up two modeling methods, considering the spatial correlation of multi input and multi output channel, do not need to provide a the prior power line channel modeling method integrated carrier network topology information and measurement data are given. The indoor low-voltage power line carrier communication channel model example, analyzes the example channel characteristics and parameters in the 2~30MHz and 2~100MHz two kinds of bandwidth, and compared with the existing models. The results show that under the same conditions in this paper the model simulation results are consistent with the existing models, but to overcome the need to get a lot of information of load impedance or large number of measurement data and the difficulty of modeling for multi input multi output Power line carrier communication provides a practical simulation analysis method, which is of great significance for simplifying the research, design and engineering application of multiple input multiple output power line carrier channel.
