论文摘要

与现有技术相比,智能反射表面(IRS)技术为毫米波(MMWave)通信系统提供了更可行的传播路径,以克服阻塞。在本文中,我们考虑了带有IRS的下行无线系统,并制定了关节功率分配和波束形成设计问题,以最大化加权总和率,这是一个多变量的优化问题。为了解决该问题,我们提出了一种基于新型的基于歧管优化算法的新型交替歧管优化算法。仿真结果表明,我们提出的优化算法在改善无线通信系统的加权总数方面胜过现有算法。

Intelligent reflecting surface (IRS) technology offers more feasible propagation paths for millimeter-wave (mmWave) communication systems to overcome blockage than existing technologies. In this paper, we consider a downlink wireless system with the IRS and formulate a joint power allocation and beamforming design problem to maximize the weighted sum-rate, which is a multi-variable optimization problem. To solve the problem, we propose a novel alternating manifold optimization based beamforming algorithm. Simulation results show that our proposed optimization algorithm outperforms existing algorithms significantly in improving the weighted sum-rate of the wireless communication system.
