摘　　要：针对现阶段D2D(Device-to-Device)通信信道分配效果不佳等问题,提出基于匈牙利(KM:Kuhn Munkras)算法的D2D通信信道分配最优化数学模型。在D2D通信系统模型构建的基础上,计算D2D通信信道传输速率,将系统中的各个变量表示在一个二维坐标系中,构建线性规划图,根据该图求解D2D用户的最佳发射功率;基于KM算法建立D2D通信信道分配最优化数学模型,实现D2D通信信道分配。实验结果表明,所提方法D2D通信信道分配最优化数学模型的实际应用效果更好,通信系统的吞吐量更大。Aiming at the poor effect of D2D(Device-to-Device)communicationchannel allocation,an optimization mathematical model of D2D communication channel allocation based on KM(Kuhn Munkras)algorithm is proposed.Based on the model of D2D communication system,the transmission rate of D2D communication channel is calculated,and the variables in the system are expressed in a two-dimensional coordinate system.A linear planning diagram is constructed,according to which the optimal transmission power of D2D users is solved.Based on KM(Kuhn Munkras)algorithm,themathematical model ofD2D communication channel allocation optimization is established to realize D2D communication channel allocation.The experimental results show that the practical application effect of D2D communication channel allocation optimization mathematical model is better,and the throughput of communication system is greater.
