D2D通信中高能效的资源分配算法研究
ENERGY EFFICIENT RESOURCE ALLOCATION ALGORITHM IN D2D COMMUNICATION
摘要
Abstract
D2D can greatly improve the scarcity of spectrum resources,but it also introduces complex same frequency interference.In this paper,we propose multiple D2D models to share the same wireless resources at the same time,and achieve the goal of maximizing the energy efficiency of D2D communication systems under the requirements of minimum spectrum efficiency.We propose a new wireless resource management algorithm.Firstly,in order to simplify the interference model,the clustering algorithm is used to complete the grouping of D2D users.Secondly,the generalized fractional programming theory is used to convert the fractional form objective optimization problem into the reduced optimization problem.Finally,we propose an efficient power control algorithm and an iterative algorithm for subcarrier allocation.Numerical simulation results show that the proposed algorithm can significantly improve the energy efficiency of D2D communication systems under the constraint of spectrum efficiency,and has good convergence.关键词
