Optimizing the Phase Shifts of RIS by MM Algorithm in RIS-Aided Positioning Systems

In Reconfigurable intelligent surface (RIS)-aided positioning systems, a proper design of RIS phase profile is important to fully explore the potential of RIS. Generally, the position error bound (PEB) is used as a metric of positioning performance, and the phase shifts of RIS are optimized to minim...
