Wideband Localization with Reconfigurable Intelligent Surfaces

2022 IEEE 95th Vehicular Technology Conference: (VTC2022-Spring), 2022
The wideband system plays a important role in high-accuracy location awareness. In beyond 5G networks, reconfigurable intelligent surfaces (RISs) are proposed to control the complex wireless environments. However, existing works related to RISs mainly focus on narrow-band systems due to the frequency-selectivity of conventional metasurfaces. This paper

Indoor Localization With Reconfigurable Intelligent Surface

IEEE Communications Letters, 2021
Recently, reconfigurable intelligent surface (RIS), which operates with the aim to manipulate multi-path signals, has been widely considered for wireless communications. In this letter, we extend the employment of RIS to indoor positioning, with the aid of ultra-wideband (UWB) technique. Moreover, the Cramer-Rao lower bound of the developed positioning
