| 摘 要： | 针对蜂窝系统中D2D通信和蜂窝通信模式下的资源共享问题，提出一种基于信噪比均衡的资源分配算法。在优化所有用户接收干扰功率和均衡所有用户信噪比的基础上，建立以最大化系统总吞吐量为目标的凸优化问题。利用拉格朗日乘数法求解凸优化问题，得到闭式解。仿真结果表明，该算法能提高D2D链路与蜂窝链路的信噪比及系统总吞吐量。 |

| Abstract: | For Device-to-Device(D2D) links sharing the radio resources with the cellular links in cellular network,this paper proposes a resources allocation algorithm based on Signal to Noise Ratio(SNR).It establishes a convex optimization problem to maximize total system throughput on the basis of optimizing the received interference power and balancing SNR of all users.It solves the convex optimization problem using Lagrange multiplication method,and thus obtains the closed-form solution for this convex optimization problem.Simulation results illustrate that the algorithm can improve the SNR of the cellular links and increase the total system throughput effectively. |
| Keywords: | Device-to-Device(D2D) communication Signal to Noise Ratio(SNR) convex optimization Lagrange multiplication method resource allocation |
