Phase Optimization and Message Passing Algorithm for RIS-Aided RSS Fingerprint Localization

The received signal strength (RSS) fingerprint-based technique is extensively utilized for indoor localization, as it does not require time synchronization. However, conventional RSS fingerprint localization schemes require multiple access points (APs), leading to a high deployment cost. In this wor...
