Design and Practical Validation of a Novel Modulation Scheme for RIS Detection and Identification

Adam Umra, Aydin Sezgin, Aymen Khaleel

A modulation scheme uses passive beamforming to encode RIS identifiers over the air and combines it with beam sweeping to lower miss-detection and false-alarm rates.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The proposed modulation scheme reduces miss-detection and false-alarm probabilities by leveraging the RIS's passive beamforming gain to enable over-the-air modulation of the RIS ID combined with passive beam sweeping.

C2weakest assumption

The RIS hardware can execute the required passive beamforming and beam sweeping patterns with sufficient precision and without introducing unmodeled distortions or power constraints that would degrade the ID modulation in real deployments.

C3one line summary

A novel modulation scheme for RIS detection and identification that uses passive beamforming for over-the-air ID modulation and beam sweeping for coverage, shown to lower miss-detection and false-alarm rates in simulations and prototype tests.
