Beamspace Modeling of Multi-mode Communications with Large Intelligent Surfaces [PDF]
2021 55th Asilomar Conference on Signals, Systems, and Computers, 2021 The use of large intelligent surfaces as antennas enables the realization of multiple communication modes even in line-of-sight conditions, thanks to the exploitation of the near-field propagation. Despite results for the number of communication modes are known for specific configurations (e.g., small antennas and paraxial scenario), ad-hoc models are ...

Initial Analysis of Dynamic Panel Activation for Large Intelligent Surfaces [PDF]
2021 IEEE Workshop on Signal Processing Systems (SiPS), 2021 Large intelligent surfaces (LIS) have the potential to be the beyond-massive-MIMO solution, even further improving spectral efficiency, coverage, reliability and other performance measures. They also open up for entirely new services, such as precise localization, environment sensing, and wireless energy transfer.

Decentralized Equalizer Construction for Large Intelligent Surfaces [PDF]
2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019 In this paper we present fully decentralized methods for calculating an approximate zero- forzing (ZF) equalizer in a large intelligent surface (LIS). A LIS is intended for wireless communication and facilitates unprecedented MU- MIMO performance, far superior to that of Massive MIMO.

Localization in NLOS Conditions using Large Reconfigurable Intelligent Surfaces [PDF]
2021 IEEE 22nd International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2021 This paper proposes a low-complexity practical algorithm to localize mobile users under NLOS channel conditions using a single base station and a large reconfigurable intelligent surface (RIS). The numerical results show the trade-off between localization accuracy and latency as well as the robustness of the localization algorithm to the presence of ...
