D2D通信中联合资源分配与功率控制算法
摘要
终端直通(D2D)技术引入移动蜂窝网络虽然能够提高蜂窝系统性能
但却带来了很大的干扰和能量消耗。为了降低干扰
提升频谱效率
同时又兼顾能量效率
提出了一种联合资源分配和功率控制的方法
用以实现高能效的D2D通信。仿真结果表明:本文提出的迭代资源分配和功率控制方案
相比已有方案能量效率有了明显提高。
Abstract
The device-to-device( D2D) communications in cellular networks impr-ove the performance of the cellular system
but bring the interference and hig-h energy cost. To reduce the interference and improve both the spectrum efficiency( SE) and energy efficiency( EE)
investigate a scheme of jointing resource allocation and power control for energy-efficient D2D communications in cellular networks. Simulation results demonstrate that by using the proposed iterative resource allocation and power control scheme
EE is remarkably improved.
