Beyond Diagonal Reconfigurable Intelligent Surfaces for Multi-Carrier RF Wireless Power Transfer
Amirhossein Azarbahram, Onel L. A. López, Bruno Clerckx +2
Radio frequency (RF) wireless power transfer (WPT) is promising for promoting sustainability in future wireless systems, but its low end-to-end power transfer efficiency is a criti…
Non-Orthogonal Multiple-Access Strategies for Direct-to-Satellite IoT Networks
Felipe Augusto Tondo, Jean Michel de Souza Sant'Ana, Samuel Montejo-Sánchez +3
Direct-to-Satellite IoT (DtS-IoT) has the potential to support multiple verticals, including agriculture, industry, smart cities, and environmental disaster prevention. This work i…
"Iridescent" Reflective Tags to Enable Radar-based Orientation Estimation
Onel L. A. López, Zhu Han, Ashutosh Sabharwal
Accurate orientation estimation of objects can aid in scene understanding in many applications. In this paper, we consider use cases where passive tags could be deployed to assist…
On the Spectral Efficiency of Movable and Rotary Antenna Arrays under Rician Fading
Eduardo Noboro Tominaga, Onel Luis Alcaraz López, Tommy Svensson +2
Most works evaluating the performance of Multi-User Multiple-Input Multiple-Output (MU-MIMO) systems consider Access Points (APs) with fixed antennas, that is, without any movement…
