With the rapid development of intelligent hardware and the Internet of Things, the bandwidth and resource utilization efficiency of related networks need to be improved. At the same time, the corresponding communication spectrum is becoming more and more scarce. At present, cognitive D2D communication technology in 5G network can establish communication link directly through communication equipment, so that two established communication equipment can realize direct communication, so as to make full use of communication resources and finally meet the explosive growth of traffic demand. How to manage communication resources and select communication links is the main research direction of D2D communication technology in 5G technology. Based on the knowledge of game theory, this paper proposes a communication channel allocation scheme and resource optimization scheme based on spectrum clustering and non cooperative game to maximize the operation efficiency of D2D communication equipment. The actual efficiency can reach about 1.5 times of the original communication efficiency. Finally, the optimization method proposed in this paper is compared with the traditional communication method. The experimental results show that this method has higher advantages.

随着智能硬件和物联网的飞速发展，相关网络的带宽和资源利用效率需要提高。同时，相应的通信频谱变得越来越稀缺。目前，5G网络中的认知D2D通信技术可以通过通信设备直接建立通信链路，使两个已建立的通信设备可以实现直接通信，从而充分利用通信资源，最终满足流量需求的爆炸性增长。如何管理通信资源和选择通信链路是5G技术中D2D通信技术的主要研究方向。根据博弈论知识，提出了一种基于频谱聚类和非合作博弈的通信信道分配方案和资源优化方案，以最大化D2D通信设备的运行效率。实际效率可以达到原始通信效率的1.5倍左右。最后，将本文提出的优化方法与传统通信方法进行了比较。实验结果表明该方法具有较高的优势。
