Comprehensive study of reconfigurable intelligent surfaces on wireless communications

RIS has the potential to raise wireless network capacity and coverage.RISs are seen as a viable technology for communication networks. RIS offers a detailed review of current state in this context, with an emphasis on their operating principles, quality assurance, directional antennas design and management system, deep learning applications to RIS-enhanced cellular networks, and RIS inclusion with other innovative technologies. It provides a standard evaluation of multiantenna aided RIS systems based on an explanation of the basic physical and networking concepts of RISs. In the remainder of this study, we will refer to RIS without losing generality. In this study we discuss about the various method and algorithms to improve and solve the performance in wireless network and RIS.
