RIS-Enabled Localization Continuity Under Near-Field Conditions
2021 IEEE 22nd International Workshop on Signal Processing Advances in Wireless Communications (SPAWC)(2021)
摘要
Reconfigurable intelligent surfaces (RISs) have the potential to enable user localization in scenarios where traditional approaches fail. Building on prior work in single-antenna RIS-enabled localization, we investigate the potential to exploit wavefront curvature in geometric near-field conditions. Via a Fisher information analysis, we demonstrate that while near-field improves localization accur...
