【摘要】：设备到设备(D2D)通信对未来蜂窝网络是一种很有前途的技术,它可以有效地提高系统的吞吐量和延长用户设备的电池寿命。然而,在蜂窝网络中,D2D通信共享频谱会造成干扰。为消除干扰,充分利用D2D通信的优势,提出了一个联合的频谱资源分配和功率控制(RAPC)方法,该方法能够实现总吞吐量最大化,同时保证D2D用户和蜂窝用户所需的最小速率。提出的资源分配和功率控制的优化问题,通过量子粒子群(QPSO)得到近似优化方案的最优解,其中的量子粒子代表资源分配和功率控制的方法,同时制定惩罚函数删除不可行的方法。仿真结果表明,该方法具有更好的性能、系统吞吐量、功率效率和最小速率比其他方法令人满意。
[Abstract]:Equipment-to-device D2D) communication is a promising technology for future cellular networks, which can effectively improve the throughput of the system and prolong the battery life of user equipment. However, the shared spectrum of D-D communication in cellular networks can cause interference. In order to eliminate interference and make full use of the advantages of D2D communication, a combined spectrum resource allocation and power control method is proposed. This method can maximize the total throughput and ensure the minimum rate required by D2D users and cellular users. The optimal problem of resource allocation and power control is obtained by quantum particle swarm optimization (QPSO), in which the quantum particle represents the method of resource allocation and power control. At the same time, the penalty function to delete the method is not feasible. Simulation results show that the proposed method has better performance, system throughput, power efficiency and minimum rate are more satisfactory than other methods.
