Energy‐Efficient Element Selection in RIS‐Assisted Backscatter Communication Systems
IET Communications, Volume 20, Issue 1, January/December 2026.This paper investigates energy‐efficient reconfigurable intelligent surface (RIS) assisted ambient backscatter communication systems with energy‐harvesting tags. A low‐complexity RIS element selection strategy is developed to satisfy both energy‐harvesting and signal‐to‐interference‐plus‐noise ratio constraints while minimizing overall power ...
