Simplified Explanation
This abstract describes a method implemented by a processor connected to a reconfigurable intelligent surface (RIS) system. The RIS system includes one or more RISs, which are capable of redirecting wireless signals. The method involves detecting wireless control signals from a transmitter and analyzing the channel state and phases of these signals. The beam-steering reflection matrix of the RIS system is then improved based on the analysis. The RIS system is configured based on this improved matrix. Each RIS in the system redirects the incident signal towards an antenna array of the intended receiver. The RIS and transmitter are located at different heights, with the RIS being a certain distance away from both the transmitter and the receiver in a horizontal plane.
Original Abstract Submitted
A method, implemented by a processor connected to a reconfigurable intelligent surface (RIS) system that includes one or more RISs, includes detecting one or more wireless control signals from a transmitter. The method includes identifying a channel state and one or more phases based on the detected wireless control signals; improving a beam-steering reflection matrix (Φ) of the RIS system based on a singular value decomposition of channel matrices; and configuring the RIS system based on the Φ. Among the RISs, each RIS is configured to redirect an incident signal toward an antenna array of an intended receiver. The incident signal is received from the transmitter. Locations of the RIS and transmitter differ by a height placement value (h). In a horizontal plane, the location of the RIS is a first distance (D) from the transmitter and a second distance (D) from the receiver.
