论文摘要
可重新配置的智能表面（RIS）的传输技术提供了一种有希望的解决方案，可以通过正确调整大量被动反射元素的参数来提高无线通信性能。这封信提出了一种基于余弦定理的相似性低复杂算法，用于调整RIS的相移，以帮助多输入多输出（MIMO）传输系统。开发了一种半分析概率方法，以得出系统的理论平均位误差概率（ABEP）。此外，通过广泛的计算机模拟支持理论分析的有效性。
Reconfigurable intelligent surface (RIS)-based transmission technology offers a promising solution to enhance wireless communication performance cost-effectively through properly adjusting the parameters of a large number of passive reflecting elements. This letter proposes a cosine similarity theorem-based low-complexity algorithm for adapting the phase shifts of an RIS that assists a multiple-input multiple-output (MIMO) transmission system. A semi-analytical probabilistic approach is developed to derive the theoretical average bit error probability (ABEP) of the system. Furthermore, the validity of the theoretical analysis is supported through extensive computer simulations.
