Position and Orientation Estimation through Millimeter Wave MIMO in 5G Systems

Understand

Millimeter wave signals and large antenna arrays are considered enabling technologies for future 5G networks.

• While their benefits for achieving high-data rate communications are well-known, their potential advantages for accurate positioning are largely undiscovered.
• We derive the Cram\'{e}r-Rao bound (CRB) on position and rotation angle estimation uncertainty from millimeter wave signals from a single transmitter, in the presence of scatterers.
• We also present a novel two-stage algorithm for position and rotation angle estimation that attains the CRB for average to high signal-to-noise ratio.
