Multiple antenna arrays play a key role in wireless networks for communications but also localization and sensing. The use of large antenna arrays pushes towards a propagation regime in which the wavefront is no longer plane but spherical. This allows to infer the position and orientation of an arbitrary source from the received signal without the need of using multiple anchor nodes. To understand the fundamental limits of large antenna arrays for localization, this paper fusions wave…

Cramér-Rao Bounds for Holographic Positioning
TLDR
This paper computes the Cramér-Rao Bound (CRB) for the estimation of the source position on the basis of the three Cartesian components of the electric field, observed over a rectangular surface area, and finds that surfaces of practical size may guarantee a centimeter-level accuracy in the mmWave bands.
Towards 6G Holographic Localization: Enabling Technologies and Perspectives
TLDR
The importance of radio localization and its role in all the cellular generations, from first generation (1G) to 6G is illustrated and the idea of holographic localization where the characteristics of electromagnetic (EM) waves are fully controlled and exploited to achieve better wireless localization is speculated.

This paper investigates the possibility to infer the position of a single antenna transmitter using a single asynchronous receiving node by retrieving information from the incident spherical wavefront by introducing a dedicated general model for different EM processing architectures.
Cramér-Rao Lower Bounds for Positioning with Large Intelligent Surfaces using Quantized Amplitude and Phase
TLDR
This paper derives analytical bounds for the CRLB for positioning with LIS when all phase information is disregarded and amplitude is measured with full resolution and presents numerical results in the form of tables including theCRLB loss due to the different quantization resolutions, which can serve as a design guideline for hardware developers.
New Aspects of Electromagnetic Information Theory for Wireless and Antenna Systems
TLDR

TLDR
This paper extends the approach to further determine the optimal antenna characteristics which maximize the capacity for the propagation scenario, with the resulting capacity bound representing the ultimate maximum achievable value if optimal antenna design and signaling are used.
Spatially-Stationary Model for Holographic MIMO Small-Scale Fading
TLDR
This paper considers the small-scale fading in the far-field, and model it as a zero-mean, spatially-stationary, and correlated Gaussian scalar random field, and develops a discrete representation for the field as a Fourier plane-wave series expansion.
