基于图论的宽带电力线MIMO信道特性研究
|
摘要
多输入多输出(multiple-input multiple-output,MIMO)技术已被应用到宽带电力线通信(power line communication,PLC)中,精确建立MIMO信道模型对宽带MIMO电力线传输技术的研究和系统设计具有重要意义。已有的自底向上和自顶向下的MIMO PLC信道模型在实际应用中都受到限制,该文主要针对三导体电力线网络,首次提出了基于图论的2×2MIMOPLC信道建模方法。该方法首先需要明确电力线网络拓扑结构和分布式参数,通过迭代列举算法(iterative enumeration algorithm,IEA)的递归运算求解前K条最短路径得出给定拓扑结构的电力线网络的信道传输函数,克服了电力线网络结构复杂时自底向上模型的局限性,同时避免了自顶向下模型对信道的数据测量。利用三导体传输线理论和测量结果验证了所提出方法的有效性,并与传输线理论方法进行比较,证明了该方法简单实用,对宽带电力线MIMO信道研究和工程应用有重要意义。
Multiple-input multiple-output(MIMO) technique has been used in broadband power line communication(PLC). An accurate modeling of MIMO channels is of importance for transmission technology studies and the design of broadband MIMO PLC systems. However,there are limitations in practical applications for existing MIMO channel models by using the bottom-up and top-down methodologies. This paper focused on a three-conductor power-line network and proposed a 2×2 MIMO PLC channel modeling approach by graph theory for the first time. In this approach, based on given power-line network topologies and cable distributed parameters, a recursive operation of iterative enumeration algorithm(IEA) in solving the K-shortest paths to estimate the channel transfer function for a particular power-line network was investigated, which avoided limitation of solving channel transfer function in the bottom-up model when the network structure was complex, and also avoided to measure the actual channel in the top-down model. The proposed approach was validated by three-conductor transmission-line(TL) theory as well as measurement results and also compared with TL theory method. The proposed MIMO PLC channel-modeling approach by using graph theory herein is simple to be implemented, and it's useful in broadband MIMO PLC channel research and engineering applications.
