mmWave 6D Radio Localization With a Snapshot Observation From a Single BS

Mohammad A. Nazari et al.

Summary: This paper proposes a method for localization using millimeter-wave signals, which estimates the 3D position and orientation of a user equipment based on the multiple-input multiple-output signals between the base station and the user equipment. Numerical results show that the proposed method is efficient and achieves a smaller gap to the Cramer-Rao bound.
