摘要

第6代（6G）网络寻求提高覆盖范围和效率，可重构智能表面（RISs）提供了一种创建适应性无线电环境的方法。在ris辅助系统中实现最佳性能，特别是在多天线系统中，依赖于精确的信道估计。这封信介绍了用于单独信道估计的增强方法，通过使用确定性信道模型和最佳RIS配置来降低导频开销并提高效率，解决了下一代网络大规模RIS部署中的挑战。

Optimized Channel Estimation Strategies for RIS-Aided Communication

6th-Generation (6G) networks seek improved coverage and efficiency, with Reconfigurable Intelligent Surfaces (RISs) offering a way to create adaptable radio environments. Achieving optimal performance in RIS-assisted systems, especially with multiple antennas, depends on precise channel estimation. This letter introduces enhanced methods for separate channel estimation that lower pilot overhead and improve efficiency by using deterministic channel models and optimal RIS configurations, addressing challenges in large-scale RIS deployments for next-generation networks.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
