论文摘要
这项工作研究了一种新型的同时传播和反射可重新配置的智能表面（Star-Ris）辅助全双工（FD）通信系统的有效性。我们的目标是通过共同优化星形河流的发射功率和被动光束来最大化能源效率。我们提出了一种有效的算法，以在交替优化框架下迭代地优化它们。连续的凸近似（SCA）和Dinkelbach的方法用于解决功率优化子问题。基于惩罚的方法用于在星形河流上设计被动波束。数值结果验证了所提出的算法的收敛性和有效性，并进一步揭示了与基准相比，星际 - 瑞斯和FD通信的结合的良好。
This work studies the effectiveness of a novel simultaneous transmission and reflection reconfigurable intelligent surface (STAR-RIS) aided Full-Duplex (FD) communication system. We aim to maximize the energy efficiency by jointly optimizing the transmit power and passive beamforming at the STAR-RIS. We propose an efficient algorithm to optimize them iteratively under the alternating optimization framework. The successive convex approximation (SCA) and Dinkelbach's method are used to solve the power optimization subproblem. The penalty-based method is used to design passive beamforming at the STAR-RIS. Numerical results verify the convergence and effectiveness of the proposed algorithm, and further reveal the benifits of the combining of the STAR-RIS and FD communication compared to benchmarks.
