摘　　要：为增加通信网络的吞吐量,研究宽带电力线通信网络多层信道资源分配方法。提取网络的多层信道特征,运用香农定理计算信道容量;提取载波特性,分析传输特性;建立抗干扰模型,通过控制器计算最优抗干扰策略。运用KM算法进行信道资源分配,转换为图着色冲突问题,优化颜色冲突以有效利用信道资源,实现更佳的资源分配效果。实验结果表明,实验组的总体吞吐量达到了10000bits/s,信道的整体占用率平均为79.03%,能够充分利用所有可用信道。In order to improve the throughput of communication network,the multi-layer channel resource allocation method of broadband power line communication network is studied.Extract multi-layer channel features of the network and use Shannon’s theorem to calculate channel capacity.Extract carrier characteristics and analyze transmission characteristics.Establish an anti-interference model and calculate the optimal anti-interference strategy through the controller.Using the KM algorithm for channel resource allocation is transformed into a graph coloring conflict problem,optimizing color conflicts to effectively utilize channel resources and achieve better resource allocation results.The experimental results show that the overall throughput of the experimental group reached 10000 bits/s;The average overall occupancy rate of the channel is 79.03%,which can fully utilize all available channels.
