面向通信SNR增强的RIS三维空间位置部署研究
Research on RIS Location Deployment in Three-dimensional Space for Communication SNR Enhancement
摘要
Abstract
To deal with the problem of"double fading effect"in Reconfigurable Intelligent Surface(RIS)assisted wireless communication system,an optimization method of RIS location deployment is proposed.A model of RIS-assisted wireless communication system is established in accordance with the practical application scenario,which considers that the RIS can be deployed at any location in the three-dimensional space.With the objective of maximizing the user-received Signal to Noise Ratio(SNR),the closed-form solution for the optimal deployment location of RIS is theoretically derived by numerically analyzing the relative position relationship among the base station,the RIS and the user in the three-dimensional space.The results of simulation experiments show that deploying the RIS at the optimal location obtained by the numerical analysis method improves the user-received SNR for the RIS-assisted wireless communication system in practical application scenarios.关键词
