针对放大转发两跳中继网络，提出了一种联合的中继选择和功率分配方案，以最大化能量效率，同时限制最小频谱效率要求.该方法简单易行，在绿色通信中具有广泛的应用前景。数值算例验证了分析的正确性。
A joint relay selection and power allocation scheme to maximise energy efficiency with restriction on the minimum spectral efficiency requirement for an amplify-and-forward two-hop relay network is presented. A closed-form solution of the low-complexity power allocation for such a system has been derived, which is easy to implement and has the potential to find wide application in green communications. Some numerical examples are provided to validate the analysis.
