Robust Transmission Design for RIS-Assisted RSMA-SWIPT Systems With Movable Antennas Under Hardware Distortions
Making wireless power and data transfer work reliably with imperfect equipment
Engineers designed a system that simultaneously transmits information and wireless power to multiple users while accounting for two real-world problems: incomplete knowledge of signal conditions and hardware that doesn't perform perfectly. The system uses movable antennas and intelligent reflective surfaces to adapt continuously, achieving higher data rates even when conditions are uncertain or equipment degrades.
Wireless power transfer could charge devices without cables, but only works if transmitters can adjust to real equipment limitations and incomplete information about signal paths. This framework makes that adjustment automatic and robust, bringing practical wireless power systems closer to viability for phones, sensors, and remote devices that can't be recharged manually.
