非完美 CSI 下的全双工中继网络的能效谱效均衡.

In order to optimize the energy efficiency and spectral efficiency of decoded-and-forwarded full-duplex relay network 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 factors. The simulation results show that changing the compromise factor can change the energy efficiency and spectral effectiveness of the system and obtain the performance tradeoff of energy efficiency and spectrum effectiveness.
