非完美CSI下的全双工中继网络的能效谱效均衡
Trade-off between energy efficiency and spectrum efficiency for full-duplex relay network with imperfect CSI
摘要
Abstract
In order to optimize the energy efficiency and spectral efficiency of decoded-and-forwarded full-duplex relay net-work in imperfect channel state information,this paper proposed an energy efficiency and spectral efficiency balancing strategy based on this network model.It could replace the non-convex multi-objective optimization problem to a convex single-objective optimization problem by constructing a compromise optimization function of energy efficiency and spectral efficiency.It used derivation method and Lagrange multiplier method to solve the optimal relay transmission power under different compromise fac-tors.The simulation results show that changing the compromise factor can change the energy efficiency and spectral effective-ness of the system and obtain the performance tradeoff of energy efficiency and spectrum effectiveness.关键词
