摘要
Recently, technological development in the creation of programmable metamaterial has aided progress in the development of the Reconfigurable Intelligent Surface (RIS), which has been considered one of the fundamental technologies for future wireless communication systems. In this paper, we investigate the problem of maximizing the average achievable rate for multiple users indoor wireless communication environment assisted by multiple RISs. Unlike most existing works considering single-RIS single-user scenarios or single-RIS multi-user scenarios, the multi-RIS can reflect the signals from several transmission links in all destinations. The average achievable rate maximization problem for indoor communication systems is solved by optimizing the phase shifts of reflective elements. Thus, we propose a Multi-verse Optimizer approach to solve the problem. Our simulation results demonstrate that a communication system with multiple RISs provides considerable achievable rate gains relative to baseline schemes.
