论文摘要
这项工作考虑了一个点对点链接，其中可重新配置的智能表面有助于发射器和接收器之间的通信。相对于智能表面的单独调谐元素的数量，系统速率，能源效率及其权衡得到了优化。由于渠道估计，资源分配是通信阶段和间接费用的说明，并将优化的资源分配报告给智能表面。数值结果证实了所提出的方法的最佳性，并显示了可重构智能表面的潜在增长。
This work considers a point-to-point link where a reconfigurable intelligent surface assists the communication between transmitter and receiver. The system rate, energy efficiency, and their trade-off are optimized with respect to the number of individually tunable elements of the intelligent surface. The resource allocation accounts for the communication phase and for the overhead due to channel estimation and to reporting the optimized resource allocation to the intelligent surface. Numerical results confirm the optimality of the proposed methods and show the potential gains of reconfigurable intelligent surfaces.
